I have noticed that when Sysinspector is run, the memory use for ekrn more than doubles and it is not released back to the system. I am running this on a schedule once a week. My remote users were running it once a day usually 1st thing in the morning. If the machine is never restarted it looks like the memory use will continue to grow with each subsequent run. I now believe this is what caused the issue I was having on my Win2k server a few weeks back. In that case the process hung and ekrn caused the processor use to peg at 100% indefinitely. The only way to stop it was to reboot the server. <edit> I have just done this on a few more random PC's int the office and some seem more well behaved than others. I am not sure what the common link may be.</edit> I have since stopped running this on any of my servers and only when needed on anything else. Any ideas?
