Maintenance :: Service Host - Local System (Network Restricted) High CPU Usage
Sep 8, 2012
As soon as I start an application (Cadence Allegro PCB Designer 16.5 but I don't think it's relevant) my CPU usage gets to the roof and stays there long after I killed the application and I believe I every associated process. The CPU usage is so high that the battery will be drained after about 45 minutes (It usually last about 3 hours).
According to my task manager the responsible is "Service Host: Local System (Network Restricted)". As a matter of fact, preventing the executable from accessing the network sort of solves the issue. I don't believe I need that executable to access the network but I'd like to understand what kind of network service can consume that much CPU (was actually affraid of overheating) and to know if there's a more appropriate way to solve this.
So I've been having this problem for days now, two tasks named Service Host: Local Service(Network Restricted) and Service Host: Local Service(No Network) keep using up ALL of my cpu, theyre usually accompanied by any app I have open, so my task manager is basically like this for example:
Service Host: Local Service(Network Restricted) 40% cpu usage Skype 29% cpu usage Service Host: Local Service(No Network) 26% cpu usage
If I close skype, the usage goes down to 2 percent for a brief second and then any other app I have open launches up instead of skype and uses up all of my cpu.
I've tried several virus scans and I've done my best to clean up the system but I still have this problem
I am using Dell Optiplex 3010 in my office.There are around 40 systems and all have same issue. Config is as follow
Windows 8 Genuine 64 bit 2GB DDR 3 Dell Optiplex 3010
Now the problem is there is one service Service Host: Local Network Restricted it consumes 100% disk usage and computer starts acting. I have to manually kill this process from task manager around 4-5 times to end it.
I'm setting up a new laptop running Windows 8.1. I keep finding the Windows Media Network Sharing Service keeps starting up when the PC is otherwise idle and running at 90% + CPU load for long periods. There is no demand for media streaming when the process is running.
What is this process for? Can I disable it or reconfigure it to reduce the CPU load?
Basically when I start my laptop everything is good for a while when suddenly the CPU usage goes high because of System Interrupts (~25%) and System (~12%). I have tried using LatencyMon to track down the problem and it used to give me alerting messages but now it gives me messages that are all green and nice ("Your system appears to be handling(...)").
NOTE: My drivers ARE up-to-date, but I am not sure my BIOS is. I don't really know how to update the BIOS though, it's a really weird model I have here, that has become obsolete.
*update1* Upon thinking that it might be the wireless driver or the network driver I disabled both, but it didn't drop the CPU usage
*update2*Now I get disconnected from the internet randomly... it may be the wi-fi driver after all
My task manager is showing an unusually high CPU usage by the system, anywhere between 20-30% when the computer is idling. I've run the sfc /scannow utility and it found some corruptions, which were then fixed by the DISM utility. However the task manager is still showing that super high CPU usage and no amount of restarts is changing anything. I've attached an image of my task manager.
I'm using the same programs as my old system which also had the same amount of ram (2x4GB 1600MHZ) and the usage was very low.
This PC was only built 4 days ago the current ram is 8GB (2x4GB) Corsair Vengeance Pro, 2133MHz, CAS 11-11-11-30, 1.5V
The first two days that the PC was built I noticed the idle usage at 88% and if i ran a program it would hit 100% and pretty much freeze the PC so it's not an error in the display.
Mobo is MSI Z87-GD65 and I'm running Windows 8.1 with no updates.
Probably not anything to do with it, but i'm running beta amd video drivers and it's showing my card as 5GB, I'm planning to uninstall beta drivers and run updates. Just wanted to know of others opinions.
I bought this Vaio with Core i5-3210M, 4Gb Ram, Windows 8 64 bit. I had really high hopes for it, coming from an i3. For the first few weeks it worked fine, but then it started to freeze while watching movies. Then it started happening all the time, and the cooling fan became consistently noisy for working at full capacity.
I was used to opening task manager on older systems when this happened to see if there was a non-responding program and force it closed, so I noticed Task Manager offers some more features in Win 8. Here, I see that CPU usage is high, staying always around 70% and from time to time reaching 100. At this moment, the process taking the biggest slice is called VCS System Tray with 58%.
What's perhaps more concerning, is that Disk usage is almost constantly on 100%. And by this I mean it reaches 100 and stays there for long periods of time, perhaps up to 20 minutes, then it falls down a few seconds and up again to 100. During this time the computer is excruciatingly painful to use. To even open a program takes forever. When this happens, it seems that Chrome is at the top of the list of processes with most disk usage, with about 1-2Mbps, but this sometimes changes and the list can be led by System, Utorrent, Octoshape, VCS System Tray, Communications Service...I think it's not related to any process by itself, but its nearly ALWAYS at 100%.
Finally, memory usage is also pretty high at 78%, but I guess this may be because 4Gb is not too much for this computer. I'm hoping to upgrade to 8 soon. Out of the 10 processes consuming most memory, 9 is Google Chrome (how's that even possible?).
I bought new lenovo ideapad Z400 touch 2 month ago with Windows 8. Last week i upgraded to win 8.1 and recover back to win 8 , since then i have some problems.
When I have the Task Manager open, I notice the disk usage climbing to 50, 75, 100 also the CPU , even though there's scarcely any disk activity going on, the laptop's fan is working harder and very noisy , my processor's speed and heat are jumping high without any programs on.
I tried almost anything, checked for viruses, disabled unnecessary startup programs, clean boot, but it still the same.
Today I upgraded from Windows 7 to Windows 8.1. For some reason, after upgrading, my hard disk usage is always hovering at around 60% usage and my CPU usage is always hovering at around 50%. This is when the PC is idle. When I was using 7, the disk would rarely jump over 30% usage and the CPU would never go above 7% when idle. The sound of the hard disk constantly working away is doing my head in, not to mention it's at around 50 degrees as opposed to 45 degrees previously.
In window 7 it uses maximum 2gb of ram when transfering big file, say an example a movie size of 8gb. now in windows 8 it seems it uses 6-8GB its as if file is transfered into ram first and then slowly copy into targeted disk. just what is going on here and why microsoft decided to do this? if power goes out then all the files is gone and the entire process is actually slower imho.
Is there anyway to disable this? or revert it back to similar what 7 had?
I am having problems with my memory it has jumped to 89% and stays there. I tried to restart i looked at the processes it seems that non-paged tools is taking the most. I used RamMAP tool to find this problem.
Over the past couple of weeks I have been getting high disk usage on my computer, causing it to run extremely slowly.
Just after I took the attached screenshot, my System went down to around 6MB/s and the "Service Host: Local System (Network Restricted)" jumped to around 16MB/s Looking in resource monitor the main things causing the high read speed are:
'rundll32.exe' and 'ccsvchst.exe' and one just called 'System'
I recently installed Windows 8.1 on my Inspiron 7520 and I noticed that during the startup the disk usage is around 98/99% of my Samsung SSD 840 Pro 120gb.
I saw a lot of posts where the users complain that, during this high usage of the disk, apps don't open, the system freezes around 5 minutes and after that, there are random high usages, even on idle. But in my case this high usage lasts only few seconds (around 30s), I can open some apps with no problems and never happens again on idle, only if I restart Explorer.exe. If I restart it, it happens all again.
My question is : Is it normal? The high usage only on startup? My only worry is mess up with my SSD due this usage.
On Performance Monitor, the process which writes a lot is System. I disabled every 3rd party app on startup.
I have a new laptop windows 8.1 (64bit) 8gb RAM i7 processor which should be sufficient for the software I use. However on start-up my memory is already at around 80% and stays like that.
The most seems to be caused by servicehost (network restricted) (11) another program is IAStorDataSvc (32bits) even after i updated Intel Rapid Storage it still seems to take some memory. (My system settings are in Dutch but I guess it's pretty much the same as in English).
What could be the cause of the massive memory use?
I have high usage on my laptop lenovo g580 using windows 8. check task manager and I see cpu memory and disk fluctuating up and down to 3% can go up to 100 at times. When I open google chrome. Watch video or play games. I hear my fan turn on and i think my hard drive and i check task manager and i see the problem happening. I did a virus scan and searched everywhere online. I couldn't seem to find a solution. When I am not using the pc its a stable 3 percent but my memory is at 37 which i barely have anything installed but 1 game and a google chrome.
I have a laptop running Windows 8 Pro x64, and lately I'm facing an issue where the System process (PID = 4) has spikes of 100% of disk usage according to task manager. I can't watch a video or play a song on a media player properly, for example (there's a crackling noise and the playback is slow), because this process (System) keeps using 99-100% of my hard drive.
Even if I have just booted up and running only the essential OS process and services and completely idle, task manager keeps reporting several spikes of 100% of disk usage. Tried uninstalling antivirus (avast free), but that didn't work. I really have no clue what do to prevent this process from writing/reading so much into HD and reaching 100% of disk usage.
Ocassionally my computer will become so slow it's almost unresponsive, when I check task manager it says 7.2 of 7.9GB of ram is in use. Even rebooting it, it will come back with high memory usage, sometimes rebooting it, it goes back to normal
Most of the time it is normal and fast, I can have Chrome open and have 10 pages open and usage is about 1GB, but what causes this to happen occasionally when I'm just surfing the internet?
I have broadband from virgin media with one of their superhubs made by netgear, I have a CCTV DVR plugged into this using a regular cat5 cable, the DVR will allow you to view 4 cctv cameras via the internet,
Android and blackberry phones can both connect to the router using wifi, an IBM laptop running XP also has no problems, the only thing that does have a problem is a new Toshiba laptop running windows 8,
If the DVR is plugged into router before win 8 connects then the Windows 8 machine cannot log on using wifi, it gives message saying restricted access and has no internet access, if you unplug the DVR Windows 8 machine logs on fine you can then plug DVR back in and laptop can browse all day with no problems, if you log off then try and log on again you get the same restricted access message again ...
While trying to add folders to the Search Index, I was informed the Windows Search process was not started. When I go to the Services Console and attempt to manually start, I am given the error:
"Windows could not start the Windows Search service on Local Computer.
Error 2: The system cannot find the file specified."
So I opened an command prompt with administrative level access to run sfc and received the following error after it was complete:
"Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windirLogsCBSCBS.log. For example C:WindowsLogsCBSCBS.log. Note that logging is currently not supported in offline servicing scenarios."
The CBS.log file is too large to upload to here or paste into pastebin, so here is a dropbox upload of it:
What other way, aside from a repair install, do I have to fix my missing files and services?
Processor: Intel i5 2500k @ 3.3GHz OS Name: Microsoft Windows 8.1 Preview with Media Center Motherboard: Z68A-D3H-83 Installed Physical Memory: 8.00GB
I just bought a brand new Lenovo U310 Touch and so far I absolutely love it. The only thing I noticed that struck me as odd is that when I look in Task Manager it shows that I am using around 60% of my available memory, but there are no processes taking up anywhere near that much. I also have a desktop I built and its memory usage is nominal when idle so I know this isn't a "standard feature" or anything.
EDIT (5/4/13) - Finally figured it out, it was the ExpressCache program, used a couple tutorials to isolate where the memory leak was and from there I found it was in the running files of ExpressCache, I just went to Uninstall Programs, hit "Repair" on the program and now everything is all nice and happy, no more memory leak.
Lately I have noticed a high disk usage with the computer using task manager. Things that cause this spike is conducting normal operations just as opening an application or the web-browser.
I do not recall seeing any disk usage on task manager for the past few weeks except yesterday (perhaps I did but I do not remember). It appears to me as if those application are using the HDD as RAM even though there is space on the 8GB memory. So I am not entirely sure.
I would like to know if it is normal for applications such as Chrome to be using the disk space? And if so, what may be causing high disk usage?
