Getting A "No Buffer Space Available" Error At Random?

I have a seemingly random problem that will keep me from connecting to the 'net. After a period of time, haven't seen any specific amount of time, just after a while, I can't make new connections to the 'net, old connections aren't effected. My email program reports "No Buffer Space Available" and Minecraft reports

Failed to update news<br>java.net.SocketException: No buffer space available (maximum connections reached?): connect

I only have Skype and Chrome running at all times. Did a scan with AVG and no viruses, did a scan with Malware Bytes and nothing found with that except a couple of cookies, so I am not entirely sure what is causing this issue. It's annoying as the only fix I've found for it is to reboot the computer, which means saving everything I'm doing in Chrome, book mark pages I plan on returning to later, etc so I can reboot. Never had this issue in Windows XP neither, not until I updated to Windows 7 did I start getting this error. Would have posted sooner but I couldn't get a specific error message until Minecraft spat out that one last night.
