This seems to be a some kind of desktop/laptop power/resource saving feature that does not take Web UI to the account. CUPS will immediately start up again if I open the printing dialog or something.
When I read Stephan's error log as well as my own, it reads: "I [30/Aug/2016:08:42:33 +0200] Printer sharing is off and there are no jobs pending, will restart on demand. I [30/Aug/2016:08:42:33 +0200] Scheduler shutting down normally." Maybe some kind of xinetd setup would make it possible to shut CUPS down but start it up when one tries to access the web UI. Please do not expire this bug, that is not a solution. and Stephan has provided the requested error log. WONTFIX would be a better solution if this is the way it is intended to work. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1598300 Title: cups hang after a while Status in cups package in Ubuntu: Incomplete Bug description: after 6 minutes or so, cups is not responding. it do not produce error on the log, just stop working, worse, it exit with 0 ⌌—————————————————————————————————————————————————————————————————————————————————————⌍ |root@cupsmachine :~# systemctl status cups | |● cups.service - CUPS Scheduler | | Loaded: loaded (/lib/systemd/system/cups.service; enabled; vendor preset: enabled)| | Active: inactive (dead) since ven. 2016-07-01 10:31:32 TAHT; 2min 16s ago | | Docs: man:cupsd(8) | | Process: 28686 ExecStart=/usr/sbin/cupsd -l (code=exited, status=0/SUCCESS) | | Main PID: 28686 (code=exited, status=0/SUCCESS) | | | |juil. 01 10:30:01 appli-client systemd[1]: Started CUPS Scheduler. | ⌎—————————————————————————————————————————————————————————————————————————————————————⌏ I got to launch it again, so I have finish with a cron job like */10 * * * * systemctl status cups.service|grep -q 'inactive (dead)' && systemctl start cups but it is a dirty solution.
