hi,
im currently haveing the same problems......
ive submitted an ticket to support.
Its not the CPU im worried about, but the massive I/O since the upgrade to 6.3. As you can see in the pictures below, since the installation the server has been misbehaving a lot.
We've limited the IOP's to 150, because otherwise it would effect the whole VMWare site.
Weve nailed the problem generator tho:
When we disable the application shown above in the IIS-application pool, the server quites down and acts normal.
Steps we've done:
Disable Alarm Generation - no effect
SQL Trace - nothing shown
IIS Trace - see image above this kills the server
