We saw on ESX 3.5 that adding CPUs actually slowed performance, due to a bug in how the processors were accessed. Dropping to 1 or 2 helped a lot, as did upgrading to v4.

They see no long queries or transactions that could be causing the high cpu usage. I did combine sql and api.

It even has BMC scratching their heads. > I have a production system that is experiencing cpu overload that runs up to 99 in the processes and sits there. > The ARSystem server is virtual machine. We thought maybe it was a MS "Patch Tuesday" issue and we removed the 10 recent MS patches one at a time and restarted the machine each time. The problem still exists after the arserver service starts. Sometime immediately and sometimes it will sit for 1- 20 minutes before it starts to hog the CPUs. > To eliminate any other OS and file system issues we grabbed a two week old backup image of the server and restored it. > The system came back ok for a short while and then started to lock up the CPU again. > Working with BMC I set the logs on and restarted.

I added a Filter that ran a 0 and the only action was Goto 1000 to jump all Filter actions that fired on the change of the Status field in question. > Still no joy. > I've disabled every piece of Notify workflow.
