I ran into a very similar problem which appeared after I installed cdemu. I believe that I have traced it down to cdemu adding a dbus service which also sets the a dbus limit.
I wonder if you would be willing verify the possibility that something similar is happening with your setup by running the following: grep "max_connections_per_user" `find /etc/dbus-1/ -type f` In a clean installation of Ubuntu 8.04 from the liveCD this returns with nothing, however my cdemu package had added a limit on this set to 20. I believe that these limits are also enforced system wide, so it is possible that an older package may have such a setting which was fine for older versions, but which no longer plays nicely given the increased usage of dbus by other system essentials. I hope I am not out of line in suggesting this... -- max_connections_per_user not set correctly in ubuntu hardy https://bugs.launchpad.net/bugs/233829 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
