We're running CAP version 4, with patches through number 7 applied, on a
network of Suns.  In particular, clients (3/60's) send print jobs to the
file server (a 3/280), which talks to a LaserWriter via a Kinetics box.
Most of the time things work OK, but occasionally the print queue gets
wedged while the printer is idle.  OK, there's an ifdef in papif that
supposedly handles just that problem.  When this ifdef is enabled, papif
notices that the printer is idle, kills off the old daemon, and starts a
new one.

Therein lies the problem.  I installed papif with this ifdef enabled,
and I immediately started getting multiple copies of print jobs.  Near
as I can tell, papif is killing the daemon before it can remove the job
from the queue.  So when the daemon restarts, it reprints the job.
Eventually the job gets finished, but only after 1-3 extra copies have
been printed.

Can someone tell me whether I've screwed up the configuration, or whether
I've stumbled on somebody's bug, or what?

thanks,
mike
