What was the resolution of the Sev 1? BAD? I can understand something not
working correctly,
My client had a situation last week where a script was executing a
DB2 stored procedure to load some data into a QA data base. The
program abended at each invocation and it had 5000 loads to do.
It looked like recursive abends at the time (we found out later it
was a script doing 5000 loads).
The latch set happens to be obtained in subpool 229 of the caller's
primary address space.
My guess is that in some way or other the value passed in was not for 6
entries.

If it resides in L1 cache type memory, then I would think that a millicoded
