I recently had an issue whereby the System Center Management service was periodically pausing on one of my SCOM management servers fro no apparent reason. I couldn’t figure out why this was happening until I discovered informational Event id 1217 in the Operations Manager event log. This revealed that the SCCM client was the culprit.
I removed the SCCM client by opening a command prompt as an administrator then navigating to the directory where ccmsetup.exe resides (in my case C:\windows\ccmsetup) and running ccmsetup.exe /uninstall
Once I did this my issues with the System Center Management service pausing stopped.
Hope this helps others also experiencing this issue
