Communication with printers fails

[kuba....@gmail.com]

Hello, we have been suddenly started to have problems with printing on fully
patched OES2 Linux cluster:

All printers have Printer Agent Status Details: SNMP Communication Failed
Some printers print well, but other printers just print out few first pages
and stop the job.

Print manager's status seems to be all OK. But in /var/log/messages, these
lines are being from time to time printed:

Apr 27 11:25:09 oes2 iprintgw[30970]: LprSendControlFile failed for printer
agent 'HP LJ1500n 12', Error 11
Apr 27 11:26:44 oes2 iprintgw[30970]: LprSendControlFile failed for printer
agent 'HP LJ 3030', Error 2
Apr 27 11:26:55 oes2 iprintgw[30970]: LprSendControlFile failed for printer
agent 'HP LJ 3030', Error 2

Apr 27 12:05:11 oes2 iprintgw[30970]: LprSendControlFile failed for printer
agent 'HP LJ1500n 13', Error 9

Also:
Problems started immediately after cluster nodes were restarted after few
months of run. Last iPrint patch was applied few weaks ago. Since then,
iprint cluster server was reloaded, but whole server was not restarted.

Thanks in advance for help.

I discovered, that this had happened because of last iPrint patch(novell-
iprint-server-6.0.20081103-0.2.2). After its deinstallation, every suddenly
worked fine and fast on previous version (novell-iprint-
server-6.0.20080422-0.2.1).
Can I somewhere forward it for Novell to try to fix this bug? The last patch
had good stability (until restarted server and almost everything stopped
working) and I'd like to use it.
