Public bug reported:
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_enqueue_hcmd failed: -28
Dec 13 21:19:37 expresso2 NetworkManager: <WARN>
nm_error_monitoring_device_link_state(): error monitoring wired ethernet link
state: error occurr
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.d/NetworkManager restart twice + reconnecting
to the wireless network.
Full syslog attached.
