This is a very serious bug that breaks network printing in certain configurations. To be clear: its not just that cups stops and the web interface is unavailable - it can lead to not being able to print as the print server looks like it is offline to the clients:
D [09/Feb/2017:10:07:02 -0600] [Job 12] Connection error: Transport endpoint is not connected E [09/Feb/2017:10:07:02 -0600] [Job 12] The printer is not responding. I was running into this issue on some print servers but not others and in comparing the two cupsd.conf files I found out I can prevent the issue by changing BrowseLocalProtocols CUPS to BrowseLocalProtocols dnssd The real problem here is that a feature like this should have a clear and easy way to turn if off completely. I don't ever want cups on a print server stopping to save an insignificant amount of cpu cycles or memory or electricity! Applying the packages from xenial-proposed does fix it for me, but in my opinion this is a pretty serious issue that needs a quicker fix. I think the best fix at the moment is the suggestion from Andreas Krausz (kukorica) to change " the option "-l" to "-f" in /lib/systemd/system/cups.service." as it seems that is the only way to turn off this "feature". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1598300 Title: CUPS web interface stops responding after a while To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1598300/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
