Core Issue
The root cause of the problem is that Cisco CallManager cannot open the sdl file for writing. Cisco CallManager service terminates unexpectedly when the trace files can no longer be written. One possible condition is for the disk drive to run out of disk space. In the case of the MCS-7845H series, this could imply the F drive. This issue is documented in Cisco bug ID CSCee06453.
Resolution
This issue is fixed in Cisco CallManager 3.3(4)SR01. In order to resolve the issue, upgrade to Cisco CallManager 3.3(4)SR01 or later. You can download the Cisco CallManager files from Software Download-Cisco CallManager Version 3.3.
If there is a single drive server, make sure there is always enough disk space for traces.
