Hello list, On our RHEL 3, we have configured 55 networked printers, on different subnets, some directly connected to the network, some through printservers (Planet, JetDirect). The printers are also of different models, HP Laserjets, Kyocera, Avery... And we set them up with raw queue, since our application sends the formatting codes. Finally, some printers are set up as socket, some others as lpd (depends on the print server). Our network has two interfaces eth0 and eth1, and they are bonded (channel bonding) on bond0 - just thought to mention this, however I don't know if it's related. Our problem is that _randomly_ some printers print out several copies of the same job. The number of copies varies but tops at 20. We monitored the network with tcpdump and noticed that the communication for a single job or for a duplicated job are exactly the same. Except that the duplicated jobs are making the communication several times. We can therefore exclude the possiblity of a wrong communication where cups wouldn't get any answer from the printer and would retry several times. We have no clue where to look for this problem, and are thinking of some bug with CUPS when dealing with a lot of printers. What experiences do you have with similar configurations? Please let me know if you need some more information. Below you'll find the output of some configuration files, logs or other output. Thanks, Erich Excerpt of /var/log/cups/error_log.
