The installation guide for DEC's VMS Ada compiler mentions UAF quotas to be careful of, and gives suggested quotas. When I've been a system manager at sites with DEC's VMS Ada compiler, I have always given the Ada accounts _at least_ DEC's recommended minimum. Increasing these UAF quotas has always been an early step in my debugging methods, right after finding that installation guide in my office.

I think there's a tool available from DECUS which diagnoses what resource a process is MWAITing for. There's the MWAIT package and FREE_RSN.
