Cause
A VOB server process is running on another ClearCase server. It needs to be tracked down and terminated.
Diagnosing The Problem
The VOB is mounted but a simple describe of the VOB notes that the vob_server process can't start.
A look at the logs at the exact time of the describe note related errors which indicate the vob_server processes are already running.
A check of the system with a ps -ef shows no process running and the error noted in technote 1219443 is not related to this problem as the VOB isn't on the local box, rather it is stored on a NAS or external storage.
The problem in this case was that another server had the VOB server process started already.

cleartool: Error: Problem starting vob_server for vob myhost:/ccase/test.vbs
cleartool: Error: See albd or vob error logs on host myhost
Resolving The Problem
Kill the VOB server process on the other system and run the ClearCase operation again that had been failing previously to confirm the problem has been addressed.
You should also look for an old .pid file in the VOB storage folder. The .pid file should be removed,
