RE: Job cannot create any more spooled files

By default a job can have up to 9999 spool files.  On recent OS release
that limit has been moved to the system value QMAXSPLF and can have a
value of 9999 through 999999.  So you can change the system value to
extend the job's runtime but it will still need to be restarted
eventually.  Also, the job itself will slowing use more resources as it
will have to maintain this list.

A solution that doesn't change the system value would be to put a
counter in your loop.  Whenever the loop hits 9000 or thereabouts, the
job can re-submit itself and then end.  That way the spool file limit is
never reached and a new job is started every 9000 minutes.
