I would test a system with patch 2 and install the 5400 Engine and see what the outcome is. Also, what processes are spiking the CPU? To get a real understanding of what's occuring I would run Process Monitor while reproducing the issue and save it in PML format. Then call and open a support ticket so we can review the PML.
Didnt realize I didnt have the latest Engine... still on 5301.4108. Will test with 5400. Shouldnt the automaticall pulls from McAfee get the latest engines automatically if you have it set to "all packages"?
There is not a process that is spiking the CPU when it freezes up... just seems to "go away" with no specific pointer as to what is happening. System just stops responding and eventually you cant do anything.
Will post back after testin 5400.
Currently the 5400 Engine is an elective download. The auto update will be posted on November 18th. KB66741
I look forward to the results of testing the engine.
