This seems to be the same issue as bug #959195. Sergey, if you don't have any custom CUPS subscriptions set up, can you please delete all of them with these commands:
sudo stop cups sudo rm /etc/cups/subscriptions.conf* sudo rm -r /var/cache/cups sudo start cups (See the aforementioned bug for a more detailed description.) The amount cups dbus notifier processes should go down immediately. ** Changed in: cups (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999295 Title: Memory leak via creation of multiple identical processes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/999295/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
