Cause: Your session and another session are waiting for a resource locked by
the other. This condition is known as a deadlock. To resolve the deadlock, one
or more statements were rolled back for the other session to continue work.
Action:
Either:
1. Enter a ROLLBACK statement and re-execute all statements since the last
commit or
2. Wait until the lock is released, possibly a few minutes, and then re-execute
the rolled back statements.
