A couple of things:

1.      Stay out of the QSPL library.  It's not nice to fool with mother nature
(you'd think that was funny is you're over 45), and these things are for
IBM's use, not yours.

2.      These multi membered files represent the contents of queue objects.
Clearly all output queue and job queue contents go here, I think data queue
and message queue also.  Clearly most of the space is stuff in output queues.

3.      The rules for output queues are a follows.  When a job needs to create a
spooled file, it looks for an appropriate member in QSPL to stuff the data
to.    If no empty member is available, one is created.  You may think that
your spooled files are in the *OUTQ object, but this is an allusion.  When
the spooled file has been printed (without SAVE(*YES)), the member in QSPL
is cleared.  Empty members hang around until:

a).     You remove them with a RCLSPLSTG command.  or
b).     They are cleared by the system based on the system value QRCLSPLSTG.
(The default is that empty members unused for 8 days are cleared the first
time in any day that an output queue is referenced [with WRKOUTQ] or the
spooled files for a job are referenced [with WRKJOB or DSPJOB]).

4.      The size varies based on the contents.  Spooled files in output queues,
or course, represent most of the size.  The size of the empty members is
relatively trivial.

5.      The QTOTxxx system values control the number of (QTOTJOB and QACTJOB)
control the total number of job structures in the system for total and
active jobs, and have nothing to do with QSPL.
