Public bug reported: When using CUPS filters, these filters can take a few seconds to complete.
In this case no documents are allowed to be lost on printing failures, so we used to set "MaxJobTime 0" in cupsd.conf which worked on Ubuntu 14.04. With cups on 18.04, you get the following message in /var/log/cups/error_log whenever the filter takes a little longer: I [12/Nov/2018:14:43:26 +0100] [Job 18] Canceling stuck job after 0 seconds. Then, the job is deleted and lost. "MaxJobTime 0" is documented as "indefinite wait", but apparently cups treats is as "wait almost not at all". This issue appears to have also been filed upstream: https://github.com/apple/cups/issues/5438 Temporary workaround is to set the MaxJobTime to a very large value instead (e.g. 3 years) ** Affects: cups Importance: Unknown Status: Unknown ** Affects: cups (Ubuntu) Importance: Medium Status: Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1804576 Title: MaxJobTime=0 results in jobs being cancelled immediately instead of never To manage notifications about this bug go to: https://bugs.launchpad.net/cups/+bug/1804576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
