We have recently experienced ~1,000 systems that have the SCCM 2012 SP1 client crashing every 5 to 10 minutes. The SCCM 2012 environment is SP1 CU3 and most SCCM clients are running the SP1 version of 5.00.7804.1000.

The following errors are written in the Application Event Log every time this occurs:

Any assistance or guidance is greatly appreciated.  Thanks!

Yes, I know that this is an old post, Im just trying to clean them up. Did you find the answer for this?

By change do you have McAfee and have you told McAfee to exclude ccmexec.exe from AV scanning?

We having a very similar issue, the ccmexec.exe keeps crashing every 10 seconds! did you find a solution for this?
