Exchange 5.5 SP3 100% CPU Utilization

Locked

I have MS Exchange 5.5 SP3 running on WinNT SP6a. Mail is coming in and going out with no problem, but Task Manager shows 98-100% constant CPU utilization by STORE.EXE. I’ve rebooted, but to no avail. The clients aren’t experiencing any problems,but I have no idea what would be eating up resources like that — only 25 users. Any help would be greatly appreciated!

I read that and we already had SP3 installed, so that wasn’t the issue.

You haven’t said anything about the hardware or whether this situation is new but Exchange is extremely RAM-hungry and on a low-end server with limited RAM (e.g. a Pentium-75 with 64meg of RAM), it is not unusual to see high utilizations but not usually pegged at 100%

If this situation is new on a server that had previously been much more mellow, I would tend to think your database is corrupt and I would run an off-line defrag using eseutil as an initial diagnostic measure.

The other thought is that if you’re using an Exchange-enabled virus scanning program (like GroupShield), this can also cause extended periods of pegging the CPU.
