SEPM is killing my server
I installed SEPM on my SBS 2003 box about two months ago and then pushed SEP itself out to a few of my client computers (I did not install SEP on the server itself). In terms of performance, everything was running fine--there was no notable slowdown and all applications still ran correctly. Yesterday, however, users began to complain about losing their connection to the network (not losing their shares entirely, but briefly losing the connection). I opened up the task manager and the server's normal ~5-10% CPU usage had shot up to somewhere around a constant fluctuation from 70-95%. I looked at the processes to see what was causing it and noticed "javaw.exe", which had never caused any issues before. It would continually appear, sap CPU power for a few seconds, then disappear. I remembered that SEPM used Java, so I killed the SEPM process and the server immediately settled down to its normal operating range. As a test, I then started SEPM again and my server went back to maximizing its CPU.
Figuring that this might be an MR0 issue, I upgraded to MR1 this morning but it hasn't fixed anything. As things stand, SEPM is shut down and none of my workstations are receiving updates (not that they were anyway, but that's a different issue entirely). If nothing else I could just install it standalone on the individual workstations but that would be an administrative nightmare and I'm not particularly fond of that route. Any ideas or suggestions?
