The best you can do is pray that it is not a keep longterm that causes
the
problem.

Have you used LOCKMON when the problem happens. W LTERM should show the
long term locks.
A RELEASE ALL will let it go, but you till need to find out where it
happens and when, in order to issue the release at the correct time.

Since a longterm lock is held by the lterm, it can be very difficult to
find out what program it comes from.
An implicit lock, or a keep (without longterm) only lasts for the length
of
the run-unit so those are much easier to find, if they cause trouble you
will be able to see the executing program and the many locks held by
that
program.

The keep longterm exclusive is especially problematic as it is usually
used
for protecting data from being updated in between run-units, otherwise
an
obtain keep exclusive would be just as good.
If something unexpected happens between the two run-units and the user
starts on something completely different, the release may not happen, or
at
least not for a while.

I don't know - as I wrote it is in TSTLCK95 - and this looks like rather
old code (don't know whether it was custom?)
(and in something like ADDPOITM, then I really don't ""get it"")

Question - how long do locks hold?

Meaning - like an implicit lock vs an explicit lock vs a KEEP
LONGTERM ( and perhaps a KEEP LONGTERM xx UPDGRADE EXCLUSIVE'




If the KEEP LONGTERM UPGRADE EXCLUSIVE is the problem - should a RELEASE
ALL make it let go?

(Because it appears the locks involved in the stalls seem awfully
persistent.)

Thanks!!
