Recently added another context to utilize Novell Messenger 2.2.0 and have started seeing many "[0x8605]: cn=username,ou=Context,o=ETMC - Unable to get the semaphore lock" errors in the logs.

Searching Google for the above error I find a reference to TID 10091678 but it's not available through the Novell Knowledgebase, or I just can't find it.

Anyone have clues on the cause/fix for these errors?
