Six months to a year ago, someone on this list mentioned a problem
with message files and received some clues as to what his/her problem
was.  The answer had to do with the FLIMIT on the message files and
the need for room to record the IPC Open records.  I don't have copies
of the specific HP3000-L messages, but have since run into the same
problem.
 
Be sure that the FLIMIT on the message file is strictly greater than
the expected number of simultaneous opens against the file.  We have a
customer whose applications were accessing a message file with an
FLIMIT of 18.  When the 19th FOPEN occurred, all activity on the
message file halted.  Not just the 19th process, but _all_ of them.
 
Aborting any one of the 19 would start things up again.  Increasing
the FLIMIT on the message file in question solved the problem.
 
Moral: don't be stingy with the DISC= parm.
