I have done some tests to investigate the problem. After removing the patch for forward-porting the CUPS Broadcasting/Browsing and running the resulting CUPS for a week I did not get any crash any more, returning to the original version gave me one crash every day or every two days. Then I tried the attached patch to set the needed locks for using Avahi in a threaded environment, but instead of crashing CUPS gets stuck, still running but not responding any more. This is even worse as in the case of a crash Upstart restarts CUPS and so CUPS stays available.
So as the patch for CUPS Broadcasting/Browsing is planned to be removed again in Raring, I suggest for an SRU in Quantal only to suppress the Apport pop-ups of the crashes somehow, as a workaround. I talked with pitti on IRC about this possibility. Setting to "Triaged" in Raring as the problem will go away with the planned removal of the patch. ** Patch added: "dirsvc-add-avahi-threaded-poll-lock.patch" https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1086019/+attachment/3459235/+files/dirsvc-add-avahi-threaded-poll-lock.patch ** Changed in: cups (Ubuntu) Milestone: None => ubuntu-13.04-feature-freeze ** Changed in: cups (Ubuntu) Assignee: (unassigned) => Till Kamppeter (till-kamppeter) ** Changed in: cups (Ubuntu Quantal) Assignee: (unassigned) => Till Kamppeter (till-kamppeter) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1086019 Title: cupsd crashes regularly (daily) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1086019/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
