When attempting to start a StarTeam Remote Cache Agent, it failed and displayed the following error message in the command prompt:

Cache Source[1]: Failed to create cache update timestamp file 'C:\.MPXCacheAgent\Cache\*.stjts': Permission denied

File extensions .stjts is a special file type used by StarTeam to track a specific timestamp, while the filename is the StarTeam ServerGUID, a unique value supplied by the Server.

Example:
Cache Source[1]: Failed to create cache update timestamp file 'C:\.MPXCacheAgent\Cache\8bbe4a22-5d61-4f98-95ed-cc83cbe54814.stjts': Permission denied

"8bbe4a22-5d61-4f98-95ed-cc83cbe54814" is the ServerGUID of the StarTeam Server Configuration.

The error message suggests that there is another remote cache agent configured to access the same StarTeam Server Configuration on the same machine. As the generated file is already locked by the other remote cache agent, this instance encountered an error when trying to access the .stjts file.

The design is such that only one active remote cache agent is allowed for a StarTeam Server configuration on a single machine. Hence, the second remote cache agent, when configured to access the same StarTeam configuration, will fail to start.
