Bug Description
Binary package hint: network-manager
For some reason, NetworkManager got in a bad state:
* 100% CPU
* lots of memory used (VIRT 2800m, REF 800m) according to top
Looking at syslog:
Dec 13 21:19:37 expresso2 kernel: [291197.056347] iwl3945: Error sending REPLY_LEDS_CMD: iwl3945_
Dec 13 21:19:37 expresso2 NetworkManager: <WARN> nm_error_
ed while waiting for data on socket
Dec 13 21:20:01 expresso2 last message repeated 406068 times
etc...
So there's a problem at the kernel driver (iwl3945) level, but NM is probably not handling it in the best way.
Solved by doing /etc/init.
Full syslog attached.
Having the exact same issue after installing a NetworkManager update last night. NetworkManager process is at 60% usage, syslogd is using all the rest up to 100%.
I also use iwl3945 for networking.
Solved by sudo killall -9 NetworkManager, then gksu NetworkManager
Happens every time I boot.
