After the installation we noticed that some servers got slower. Especially our SCOM environment suffered from this increased CPU usage (SCOM being a CPU intensive application itself, didn’t have enough CPU time left to process all agent traffic). This ultimately ended up in not being able to monitor anything.

Here’s an image of the increased CPU usage (this is our SCOM report server):

mcafee_cpu

As a quick workaround we decided to do a rollback to McAfee 8.5.
Here’s an image of the decreased CPU usage:

mcafee_cpu2

So what’s causing this? No clue yet, but there are some McLogEvent errors in the eventlog (crashing McAfee):

mcafee_mclogevent

To be continued…
