Lost printer jobs

[Jakob Breivik Grimstveit]

Hi! I'm having problems with lost printer jobs printed on a "slave" cups
server (it just sends jobs over to "master" cups server).

The server recieves a lot of print jobs, but only seems to drop jobs for
one specific printer. Where can I debug this?

A script runs this on slave cups server:

/opt/cups/bin/lpr -P chrl1201 a.pdf; sleep 5;
/opt/cups/bin/lpr -P chrl1201 b.pdf; sleep 5;
/opt/cups/bin/lpr -P chrl1201 c.pdf; sleep 5;
/opt/cups/bin/lpr -P chrl1201 d.pdf; sleep 5;
/opt/cups/bin/lpr -P chrl1201 e.pdf; sleep 5;
/opt/cups/bin/lpr -P chrl1201 f.pdf; sleep 5;
/opt/cups/bin/lpr -P chrl1201 g.pdf; sleep 5;

In this test run, master cups server (on
http://master:631/printers/chrl1201?which_jobs=completed) reports only
three recieved print jobs - these are printed. Where is the four other
documents?

I have a similar printer called itl401, when doing the same print
commands for that printer, all jobs are going out as intended.

error_log on slave cups server reports this relevant information during
the prints:

I [17/Jun/2004:09:32:38 +0200] Job 1313 queued on 'chrl1201' by 'root'.
I [17/Jun/2004:09:32:43 +0200] Job 1314 queued on 'chrl1201' by 'root'.

I [17/Jun/2004:09:33:03 +0200] Job 1318 queued on 'chrl1201' by 'root'.
I [17/Jun/2004:09:33:03 +0200] Started backend /opt/cups/lib/cups/backend/ipp (PID 29332) for job 1318.
I [17/Jun/2004:09:33:09 +0200] Job 1319 queued on 'chrl1201' by 'root'.

As you can see - only three of these print jobs seem to launch an actual
print (job 1314, 1316 and 1318).

What can be the cause of this?

Slave print server:

$ uname -a
Linux slave1.mydomain.com 2.4.9-e.40 #1 Thu Apr 8 17:03:56 EDT 2004 i686

$ cat /etc/redhat-release
Red Hat Linux Advanced Server release 2.1AS (Pensacola) 

$ /opt/cups/bin/cups-config --version
1.1.20

No print-RPM's installed:
$ rpm -qa|grep -ie lpr -ie cups|wc -l
      0

Master print server is running RHL9, latest cups from RHN's official RPMs.

Everything built from source using ./configure && make && make install
(with PREFIX, that is).

Thanks in advance for any help on this.
