Sporadic as in about 1 in 10 are affected
slow as it greater than 5 minutes, ranging up to at least an hour

iPrint running on OES2 sp3 on SLES10 sp3, all patched up to date as of
earlier this week (I see some SLES updates to apply this weekend) and
running as a focused printing VM box
Mostly P sp3 with a few Windows 7.1 systems, all should have (and have
confirmed some of those affected) the newest iPrint client I am aware
of, 5.64.00

The only 'issues' seen in the iPrint Manager health monitor are the
printers we are in process of decommissioning. (Printers turned off,
and set to uninstall from the end users). All else is a nice green
everytime I've looked at it.

The apache2 error_log shows lots of errors and warnings I can't find
anything about that might clue us the direction if I could find out
more about them. Below is a ~23 minute span during which one print job
did take long to print, so those repeat messages around 14:13 are
suspicious.
