Hi team,
When restart system SEP start working and updates in some cases on deferent deferent systems, why when restart SEP will work.
What exactly breaks, updates only? Or other components?
Run the SymDiag tool on it to do error checking:
Download SymDiag to detect Symantec product issues
updates only, but each day deferent systems, when reboot works fine, what could be the reason in general, why reboot fix the issue as seen most of time.
Maybe there is something corrupt with the engine's content and a reboot temporarily fixes it. Try a repair, try a re-install.
I'd suggest running SymDiag to see if it shows anything unusual first.
Can I get some syamntec articles if reboot can fix temporarily, since system to system issue will be deferent I guess.
There are no specific articles on this. If the issue is easily reproducible you'll need to enable SMC debugging and let it run. Once it happens you can open a case and submit the log for review. Support should have a much better understanding of what is going on and what to look for in the log.
