Currently 20-25% CPU usage, 12h after last restart of NetworkManager. I'm on a wired network (dhcp) with wireless disabled.
network-manager 0.6.6-0ubuntu5 I can't see anything related in any of the logs in /var/log. This bug is possibly related to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/162383 So I've killed NetworkManager and started it manually with the --no- daemon option. Here's the immediate output: NetworkManager: <info> starting... NetworkManager: <info> New VPN service 'ppp' (org.freedesktop.NetworkManager.ppp_starter).

CPU usage is currently zero -- I can't even see it on top, and the three NetworkManager threads have zero TIME on ps -Twu root (this was 1h+ for one of the threads just before I killed NetworkManager). I'm also running while true; do date >> log ps -Twu root | grep NetworkManager >> log sleep 30 done so I can see if there's any one event that makes CPU usage go up, and see if there's anything related in the logs. -- NetworkManager increases CPU usage the longer it is run https://bugs.launchpad.net/bugs/172700 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
