Thanks for the hint, we will look at this in cupsd.conf;
while stop/start of cupsd (to get rid of the 'socket' backends which have been sitting around) we encountered the following dramatical situation:
the stop of cupsd with the normal stop script (which just does only a "kill pid" thousands (~10.000) of defunct processes were created:
root 6515 5026 0 - ? 0:00 <defunct>
lp 6514 5026 0 - ? 0:00 <defunct>
lp 6513 5026 0 - ? 0:00 <defunct>
root 6512 5026 0 - ? 0:00 <defunct>
lp 6511 5026 0 - ? 0:00 <defunct>
lp 6510 5026 0 - ? 0:00 <defunct>
root 6509 5026 0 - ? 0:00 <defunct>
lp 6508 5026 0 - ? 0:00 <defunct>
lp 6507 5026 0 - ? 0:00 <defunct>
root 6506 5026 0 - ? 0:00 <defunct>
lp 6505 5026 0 - ? 0:00 <defunct>
lp 6504 5026 0 - ? 0:00 <defunct>
root 6503 5026 0 - ? 0:00 <defunct>
After re-starting cups they went away.
What does this mean?
