APAR status

  • Closed as returned (APAR cannot be resolved without additional info from IBM or customer.)

Error description

  • A backup of CPIH transactions in the region is observed. The
CPIH tasks are all suspended on resource type LMQUEUE. From a
dump of the region, Lock Manager shows the lock they are
waiting on is PIIMLOCK. From LM domain we can get the lock
owner's KE_TASK/TASENTRY, however, at dump time the real lock
owner has already gone and it's TASENTRY has been reused by
another task.

Kernel error table shows the real lock owner task got 999
(Runaway) abend at a previous time. DFHPIRS was in incontrol
when the  loop was detected.

Additional Symptom(s) Search Keyword(s): KIXREVxxx CPIH hang
hung backup LMQUEUE PIIMLOCK KE_TASK TASENTRY 999 0999 runaway

  • This APAR is being closed with a code of RET/AU. This closing
indicates that the Change Team has been unable to test the
proposed fix for this APAR and that no Customer was able to test
the fix and provide feedback within a reasonable amount of time.

To ensure that only high quality fixes are distributed to all
Customers, we require every fix to be tested either internally
or at a Customer site which is experiencing the problem. This
will minimize any exposure to a possible PTF error which could
later be more detrimental to the Customer.

The APAR fix is available upon application to the Change Team
via PMR. Once the fix has been satisfactorily tested by a
Customer experiencing the reported problem, the Change Team will
accept a NO-DOC APAR (which must refer to this returned APAR) in
order to provide the appropriate PTFs.

If the fix does not correct the reported problem, please contact
the Change Team via PMR with full details of the failure.
