Greetings, all! iWebMsg occasionally starts consuming 100% of the CPU on our 2 x 2.8 gHz machine with 4gb RAM, our mail store on a SAN, and daily defrag. The mail archives haven't proven useful.
It'll run fine for 1 to several days, at a low CPU load even during peak times (1-2%) and low memory (<100mb on a 4gb system with > 3.5gb free). Then all of a sudden, often NOT during peak traffic times, it jumps from 1-2% to 100% solid and runs like a giant sloth in the winter olympics. AV scanning is enabled but excludes the iMail dir and subdirs, as we use IMail AV Pro. I've even disabled the real-time scanning to no avail (and when I scan the entire iMail dir the proc usage doesn't even change for iwebmsg, so AV is not the cause). The only solution is to cycle the service, but it and iWebCal typically crash (sometimes taking smtp with it) when I try to stop them. I usually end up rebooting the machine just to make sure the system heap isn't fragmented. Anyone have any clue what's causing this? Thanks!
