Re: "Stalling"

Check the SRV subsystems. There may be an index rebuild or file reorg that
ties up low level resources. I've noticed this on small systems that are
running legacy code - especially S/36 migrated code.

On several occasions, the earliest being on pre-release code in April 1988,
and the latest on V3R1 (in 1988 a B40, now a mod 200) I've experienced a
similar 'hang' situation.  I've most often noticed it in the middle of the
night, I'm the only one on the machine, editing a source member with SEU, 
and no other jobs running.  You press a key (F4, roll key, etc.), and the
system seems to hang for a minute or two.  I reported this to IBM on
a few occasions, but we didn't get anywhere trying yo find the cause of
the problem.
