Hi,
Appologies if this has been covered but I've not found a solution yet.
We have upgraded the clients to 12.1.6 MU1 and starting getting issues where SEP would not update, Definitions were pulling down constantly but failing to install, and the client was unable to open, closing itself on the splash screen. The client was still communicating with SEPM. This occured when the machine was left on for a long period and after 4 days you would start seeing this occur. Only Windows 7 machines seemed to be effected as we did not see this issue on Windows 8 or any servers (03,08, 08 R2,12, 12 R2).
To resolve the issue I had to end the SVCHOST process that was linked to the SepMasterService. This is not a solution as with over 1000 machines I simply don't have the time to do this on every machine and I shouldn't have to.
I have installed 12.1.6 MU6 to see if this resolved the issue, which hasn't as I've started to get machines reporting the same thing that have been upgraded. This wasn't an issue in any previous version of 12.1.x
Is there a patch to resolve this issue, or do I have to roll back to 12.1.5?
