Intel PRO/1000 PT Dual Port Server Adapter & Win 8.164 bit = Memory Leak
My Intel PRO/1000 PT Dual Port Server Adapter has been working fine in Win 7 without issues but on upgrading to Windows 8.1 64bit I've found that Committed Memory would slowly increase over a week to the point that the PC would become unresponsive. The leak is related to the volume of network traffic and I can lose 1GB of Memory within 15 minutes just serving video files. It has taken me a while to track this down (and a couple of clean win 8.1 installs) and all I can say I never want to have to play with perfmon and poolmon again! Currently I'm running the stock mobo ethernet port with no issues.
