Jobs running without a program stack

Hi All

One of our customers is experiencing a strange problem with some batch
jobs running in a subsystem. The subsystem allows up to 50 jobs to run
and there are currently 35 or so showing when we do a WRKACTJOB.

A number of the jobs are in status EOJ and have been for the last 10
hours. There is no CPU usage happening on these jobs. If I do a WRKJOB
on one of the jobs with a status of EOJ and then try to display the call
stack there is a pause of between 1-2 minutes and then nothing shows.

If I then do a WRKJOB on a job with a status of RUN that shows a
function of PGM-xxxxxxxx the same thing happens, there is a pause and
nothing showing in the call stack.

There are no untoward entries in the joblog, and if I try to work with
any locks for the job the screen just hangs.

They are running v5r3 with PTF C6178530 installed on a model 595.
Everything I've found on Google points to PTFs that have long since been
superseded or microcode package GA1. I believe that being on a 595 they
should be on microcode package GA3, but don't know how or if I can
confirm that.

Has anybody seen this type of thing before or got any suggestions as to
what could be causing this?

Thanks

Jonathan
