I would suspect, that this "DING" does not refer to the program ding but is some kind of bell that is ringing in gnome-shell or nautilus.
ding does not have to do anything with gvfs or the like (except you have configured it in a very strange way). To eliminate ding as the root cause, simply uninstall ding, check that no instance of ding is running and check your syslog, which I expect to still repeat the message. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1976498 Title: DING causes gvfsd 'Too many files open' error and fills syslog To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ding/+bug/1976498/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
