I just upgraded 15 of my 16 netware servers to NW 6.5 SP8 a few weeks ago.. I was at NW 6.5 SP5... One of my servers utilization goes abnormally high after a few days of running.. It runs fine at normal utilization for a few days then starts running at 60-100 % utilization with hardly no-one logged into it.. I went into remote console and saw the following thread is consistantly at the top..

Cache Pool:0
This was in the "Execution Profile Data by Thread" screen

An ideas ??

Thanks in advance
