APAR Error Description / Circumvention

-----------------------------------------------
If a job running Job Watcher is suspended, other jobs may not be
able to end properly.  It is possible that they could be stuck
in EOJ (End of job) status.

CORRECTION FOR APAR MA45960 :
-----------------------------
Job Watcher was not correctly processing some types of
interrupts.   This caused it to be suspended while it had the
task list data structure locked.  This prevented jobs from
ending properly, since they had to wait to access the task list.


CIRCUMVENTION FOR APAR MA45960 :
--------------------------------
None.
