The server detected a deadlock situation between a number of processes that were attempting to access database information. A lock request for one of the processes is denied, to resolve the database deadlock. When server processes encounter a database deadlock, they usually reattempt the function that was in progress when the deadlock was encountered. Not all process can explicitly try an operation again. For example, migration and reclamation will eventually be tried again. However, something such as a delete volume run in a macro will only be tried again if the delete command is reissued either in the macro or the command line.
A lock request fails for one of the deadlocked processes. Server operation continues.
If a process can try again (like migration), then monitor the subsequent attempt to see if it succeeds or not. If it fails, contact a service representative. If the process or command is not able to automatically try again, then reissue the command or macro that caused the action to occur. If it fails again, contact a service representative for further assistance to better isolate the deadlock condition.
