The shop is at v5r4. No current on PTFs. Not something I am allowed

We had a spate of devices that would not connect in 2006. At the
time, I learned that there was a maximum number that could/should be
assigned to a subsystem. I passed that on to the SA, who ignored it.
The device issues continued. He *finally* contacted IBM and was
given a procedure to recover devices that get hung. He was also told
to create an additional subsystem, which he did. Problem went away.
It is now back. Three devices, in two days, so far have been hung.

The procedure from IBM was to do a
DMPSYSOBJ OBJ(PASSTHRU#LUD#LIST) CONTEXT(QSYS) TYPE(0E) SUBTYPE(EF)

scan the spool file for the hung device

If found, vary off the device and then issue this command:
CALL PGM(QSPTLIB/QPARIXEN) PARM('device name')

That works.

My question (sorry about the length of this), does anybody know if
the underlying problem has been addressed by an APAR and PTF?

If, such exists, I >might< be able to get my supervisor to persuade
the sa (who he also directs or tries to) to apply either the latest
cum or a specific PTF.

This is nuts.

Sorry for the rant and length. Just gets frustrating.

If the IBM support did not give an APAR number describing the origin of the problem being diagnosed and corrected by the noted dump and corrective actions, then as merely a guess... I think that the HIPer APAR SE43904 might identify the problem, with the PTF SI40274 on C0292540 being the fix. Since the application of that PTF along with the other PTFs on the v5r4m0 HIPer list is a good choice for a minimal level of maintenance, application of the HIPers would seem appropriate IMO; that would include SI40691, which should prevent a temporary storage leak associated with similar code. Of course applying the cumulative versus just the HIPers might be an even better choice :-)
