Server unstable when automatic update service is running
The last 2 weeks I had several phonecalls from people who were not able to open their exchange mailbox in outlook and getting an error that their profile wasn't setup right.
The problem appears to be the active directory server that has some huge CPU spikes on it's system process which causes outlook not to fetch mailbox link data in time.
When I turn off all f-secure services the server cpu flatlines to 0-1%.
Doing it step by step seems to reveal that the culprit is the update service.
When I enable that FSGKHS (whatever it is) it sometimes peaks to 10% and drops again. I can live with that since it doesn't cause freezes.
From the moment I start the automatic update service it's constantly 25-90+% and the worst part is that it sometimes goes to for example 35% then the task manager updates freeze for 5-7 seconds and then it shows 97-99% hangs another 3-5 seconds and then it drops again for 20 seconds or so and then the problem starts again.
Is this a known issue and how can I solve it?
this machine worked fine for months tho.
