We are experiencing a increasing frequency of crashes on our Publisher Call Manager of the Call Manager Service. This requires a manual restart of the service every time, and is becoming a cause of concern.
The system event log message is this:
The Cisco CallManager service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 60000 milliseconds: Restart the service.
In regards to this I have followed up the advise given in the following article
This problem on our network was resolved using the perfmon....
The perfmon showed that scandisk was scheduled to run at 100% CPU utilization between 1am and 2am. (Hence starving Callmanager of resources and once call manager is starved of CPU for about 15s it crashes) These is usually the time that the crash occurs.
We then changed the setup for scan disk at this hour to use 60%.
This has resolved our problem.
I suggest you use perfmon to see whats running especially if drwts32.log does not show anything
