Error description
Creating or deleting hyperlinks that span VOBs (common in a UCM setup) in IBM Rational ClearCase can lead to a situation where two processes are waiting on each other for a lock on one of the VOB databases. This will lead to the Dead Man Lock Timeout to be triggered, making one of the two operations to fail. Symptoms: db_server(14591): Error: Deadman lock timeout. Client "clientA,pid==18769,euid==UNIX:UID-num, No command" idle while holding locks. db_server(14591): Warning: "clientA,pid==18769,euid==UNIX:UID-num, No command" cmd: db: db_arrow_get held for 60 seconds a "r" lock in the usual area in <vob-storage>/db! Workaround: Retry the operation
