.mkv Thumbnail Memory Leak?
May 16, 2011
About a month ago I acquired a large .mkv file. Cutting to the chase, I deduced that when, in explorer, I simply clicked on the folder containing this file, my available memory started to disappear about 10-20MB a second until it was depleted; at which point system performance came to a near halt. I also eventually found out that it was the process explorer.exe that held all of this available memory, EVEN THOUGH the task manager AND resource manager showed that explorer held a steady... 25MB. On my 4GB ram system, after just about a minute, all 2.5 gigs were gone and when the explorer.exe process was ended, all that mystery memory re-appeared.Booting in Safe Mode, clicking on this folder did not produce the same result.Over the next few weeks, I acquired more and more .mkv's. NOT ALL OF THEM create this problem, but about 40% of them do, with the exact same symptoms. I tried disabling thumbnail previewing on individual files AND folder thumbnailing, and it STILL caused this super annoying issue.I can not move these large .MKVs to another hard drive unless I am in safe mode. not acceptable.

i am having a problem with my memory getting tied up / used up and not being able to access it again until i reboot.
machine: dell xps studio 8100
os: win 7,
processor: i7 2.8
ram: 16gb (max it will take)
video: ati radeon 5700 (running 3 monitors)
versions: as far as i know i am running current versions of everything, including video drivers, flash, chrome, etc. (i've tried running chrome with both the build in version of flash and the system version -haven't seen a difference)
browser: i nearly exclusively run chrome / canary with auto-updates so am at the latest builds.what seems to cause me to use up / run out of memory is after i play videos (Internet, netflix, etc.), the memory seems to get used, but is not returned to the system, even if the browser is closed and re-opened.right now for example things are working fine; i rebooted my system a couple hours ago (but have not played any videos). i have adobe lightroom running, picasa, chrome and canary (currently 4 web browser windows open with 52 tabs open). task manager currently shows me using 8.20gb of ram, that seems pretty reasonable to me.
normally my system will keep running properly (if a program is closed, memory is freed up) right up until i start to play any videos (Internet, netflix, etc.) then it will start using up more memory. (of course i expect it to use more memory during playback) however, even if i restart the browser, the memory does not get freed back up. for example, just prior to the reboot, with everything closed, i was using right around 8gb of ram. once i rebooted, i was using 1.something gb of ram prior to opening any programs.however, once i start playing some videos, i never seem to be able to get my ram freed back up again unless i reboot the whole system. this is not just a problem with how much memory the system shows as being available, i frequently actually run out of memory. (task manager will show me as using around 15gb and then everything starts swapping out like crazy).

I find that if I run chkdsk and watch the memory usage in task manager it jumps by about 50MB every 2 seconds or so until it either finishes or hits around 3.2GB at which point my physical memory shows 99% used (I'm running 4GB), and the system of course slows to a crawl.f you just run a quick chkdsk on your boot drive you may not notice it, but try running something longer like chkdsk /r on a flash drive or chkdsk /f on a bigger internal drive (but not your OS drive as this would require a reboot) and watch the memory usage climb. I have duplicated this on both systems I have running Windows 7. My XP machine (checking the same USB flash drive) uses a much more normal amount of memory for chkdsk (20 - 30 MB).

Memory Usage Goes Up Gradually (Memory Leak)When I starting the Windows (in the first few hours) everything is normal But after 1 day or 2 (sooner or later) the amount of available memory gradually goes down and the physical memory usage increasing. This increasing, continues until the memory usage reaches near the 88% and at that point , there isn't any memory available to operate any software . Also when memory reaches that point, I can't access any drive in the HDD; because everytime I want to open any folder, the following error appears :c: is not accessible.Insufficient system resources exist to complete the requested service At this point, I even can't shutdown or restart Windows normally; I must restart windows manually by pressing the restart button.after restart, everything goes to normal again; but this problem appears again and again ...

Reading around I thought IE eliminated it's memory leaks but I definitely have it when I use IE8. I typically have three windows of IE8 open and within one will have multiple tabs, maybe five or six at the most. Over time memory usage definitely grows and is not reclaimed as tabs or even windows are closed. Only way I can reclaim memory is by closing all windows and putting computer to sleep. When I awaken it and start again memory usage is back to it's initial state. But then it will grow again as I use IE8. Seems to happen no matter what websites are visited so I don't think a specific site is causing the problem.

I was just downloading somes big files with jdownloader while watching a movie, but the system was slowy getting laggy, so I checked the memory usage and i was almost full (90% of physical memory in use) and perfmon could not show me anything.
Right now, about ten minutes later, the memory usage is still the same, I killed jdownloader, java and kmplayer , but it still the same. I cant find who is guilty. I post some screens.

Notes : I use nod32 AV (not smart security). Superfetch is off.

To start, I have Windows 7, on Sony Vaio laptop. I have been working on the issues with the malware removal team, but now machine looks clean, I am still having issues. When starting the computer and going to the task manager, I can watch explorer.exe start at about 18K memory usage and then grow constantly until it is running with almost all of the computer's physical memory after about seven min. I cannot get the context menu to show up after a few min by right clicking on anything. I had been experiencing "freezing" while playing Eden Eternal (an online role playing game) before that, which made me consider malware and seek help here at BleepingComputer. The freezing has ended, last time I played on that machine at least, but now there seems to be some issue with the explorer.exe taking all of the memory. I haven't been using the machine since I don't trust that there's not something running in the background that shouldn't be. In resource monitor there were "connections" that had "-" for both the name and the PID, but I don't know if that was the malware of if that's normal somehow? Issue with explorer.exe seems to be limited to only one user account, and not the other one. That is to say that if I log on one of the other accounts explorer.exe behaves normally, as far as memory usage.

I have a ASUS Sabertooth mobo, overclocked. Performance-wise it runs fine.. high spec's. I used standard ASUS AI II software to set and check stuff like temps. Also works fine. But that software comes with a memory leak in atkexcomsvc.I've now de-installed and am going to check other versions + contact ASUS if needed.

Whenever I try to run "EN_Fallout_3_DLC", I get a memory leak problem. My RAM usage is at 97% with 3 gigs of RAM.
The only error message I get is this one.
Edit: Fixed the problem by extracting the files to a different location

In the last week or so, I have to reboot my pc almost every day because the RAM usage gets up to 93% and I can't do anything, even launch taskmanager. When I've caught it before it was too full, I saw that almost nothing was listed as using RAM (system was at like 80MB). Essentially, RAM is "in use", but the use is not explained by taskmgr or perfmon.I'm prepared to learn that it's a BIOS or mem controller issue, but it never happened in several years of XP and Vista on the same rig. Also I see I'm not the only one with the same issue on Win 7 64bit: Win 7 64bit Ram Filling Up Problem?

In both build 7048 and 7068 I have massive memory leakage going on in the gadget sidebar, and can't solve the problem aside from restarting the process to clear the memory.
Is MS aware of this? And is there a fix in newer builds? Otherwise, any useful advice?

I used to be able to view the cursor thumbnails like normal. But recently, the cursor thumbnail wouldn't show. I've attached a screenshot of it. I am still able to change my cursor, and it works fine, it's just, in the windows explorer the thumbnail of the cursor shows a Photoshop icon. Only the .cur file is affected, the .ani is not.

I'm looking for a way to enlarge the thumbnail preview in Explorer. A person is scanning in PDF documents in large amounts and then using the thumbnail preview wants to be able to rename them from the default scanner assigned name. The current thumbnail size isn't big enough to see enough detail to rename the file without opening the document.

When I hover over a window in the taskbar, I only see words instead of a picture of the window; and I would like to change that. I have changed to an Aero Theme etc, but nothing is happening. I don't think I'm an admin on my computer. Please explain answers in layman's terms, I know nothing about computers.

Adobe PDF e-Books can have a preview on Windows Seven, if Adobe Reader is installed.Similar stuff is present in Windows 7 for a lexicon of filetypes: Supported file types for thumbnails/previews - ResourceSpace Documentation Wiki But, unfortunately enough, we still lack a tool/ third-party app to enable thumbnail previews for other filetypes, that we often use in daily life, (for example *.pdb, *.chm, *.epub ebooks etc). Even if, we have a third-party viewer installed for all of them, the thumnail preview never appears (instead, they take up the filetype-icon)Many Media files can have icons with appropriate players/codecs installed: FAQ - Thumbnails But, works need to be done for the e-book sector.Similar issues have been already addressed here on this forum, so I don't think, our experts can't make it.Photoshop PSD files - Enable Thumbnail Previews - Windows 7 ForumsView Photoshop PSD files in Windows - x64 PSD CODEC for Windows 7, Windows VistaFixes for 64-bit Adobe Reader preview handler and thumbnails Some More Resources from Microsoft are Linked Here: File Type Handlers Thumbnail Handlers Building Thumbnail Handlers Thumbnail Handler Guidelines

Must be one of the most often asked question, but I haven't found correct reply yet - how to disable Windows 7 64 bit File manager to display video thumbnail preview on right panel?
regsrv32 /u shmedia.dll doesn't work - file not found.Preferred is to disable all video extensions with the same option, as there are rare formats which I'm not aware, but the slow PC down or may hang PC for several minutes.

Usually I have opened a lot of excell files and they are very similar each other. I recognize them by the title on the thumnail on windows taskbar. If I click on a file that is open in backgroud it switch on desktop, but if it is already on desktop it goes to background.
This is very unpleasant to me. When I click on a thumbnail I want THAT window. What can I do?

i like many others have the problem of all thumbnails being spontaneously deleted every other day or so , and all the 250mb worth of thumbnails being slowly generated again only to be deleted..which is a major inconvenience since my processor is comparatively slow and videos take time for thumbnails to be generated.i found that the deny permission for the explorer folder where the thumbnails are stored does indeed work, however i noticed that while i have this workaround enabled, windows aero starts lagging (the scrolling of explorer pages, even firefox pages, and any graphical effects start occurring in short jerky steps) which i again hate. as soon as i removed those deny permissions (and the thumbnails spontaneously deleted) i haven't encountered that aero lag...so its not my graphics card or driver.i have currently disabled all thumbnail generation, folder browsing is behaving very fast but it just doesn't look good for pictures...for the videos its livable with.so any way i could limit thumbnail generation to pictures files only?

Running Windows Ultimate 7 x64.I have had the problem a few of you have had with the thumbnail previews on the Superbar flickering when you mouse over the icon.Its deeper than just the superbar screwing up. When this happens I cant highlight and play more than one song at a time with WMP Have to minimize windows just to return to browser and switch back and forth to windows explorer.I have to reboot my PC just to play a DVD folder or DVD disc.The problem started well into 6 months or more of using Windows 7 so I knew it was a problem with either some software I installed or a Component problem. I use Acronis for back-ups and have saved full back-ups of Windows 7 that I know are non-problematic , so after restoring a good image on a freshly formatted partition the problem remained.Tried all the obvious things like video drivers and all but still felt it was in the motherboard chipsets. Something had gotten corrupted or changed.
I have a Gigabyte MB and downloaded the drivers for Windows 7, installed.still there. Tried north bridge and south bridge.What I ended up doing was installing Windows XP x64 on a extra partition which allowed me to use my original installation disc for my motherboard and was able to individually install the drivers for both chips...and after the installation of the south bridge, the computer needed to reboot, at which time it went into a deep process (screen display with please wait or whatever) that took several minutes to complete.I dont remember it ever taking that long to complete .....talking ...like....6-8 minutes. I knew something good was happening.I know these drivers are for XP while in XP but I really wanted to do this just to see if it might get in there and root around deep in those chips since they are the original drivers.I never used XP x64 before with this AMD x2 5600+ I am currently using so I spent a couple hours installing a few programs I use a lot and testing them.Finally I rebooted back into my 7x64 (use EasyBCD) and have not had one problem with it yet. It has been 2 days since I did all this.
