I just saw that new cups packages have been released but without this bug being fixed. That's really sad because this patch has made the difference for our print server. Without it I had so manually kill hanging and CPU consuming CUPS (socket) processes every other week or so. Since applying the patch some moths ago we didn't have a single issue and the server works as expected. Our environment is not so exotic, we have 20 printers configured and the issue happens with HP LaserJet 4050 and 4100 devices. Simon: we do plan to fix this CUPS bug (and several others) in the next scheduled update. There were some other fixes that were ahead in the queue. Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: In some circumstances the standard CUPS backends (which transfer data to the printer) could get stuck in a loop consuming CPU cycles. This has been fixed by adjusting the main data processing loop shared by all the backends. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2011-0095.html |
