RE: NetworkManager process dies sometimes

we're running release version, we used apt-get install in the ubuntu system (arm platform).

Will send error message when i can reproduce it.

At this point, we do see such things, even though NM is still running and ping still works for both eth ports.

/var/log/syslog.1:Jan 10 16:50:33 utilite-ubuntu-desktop NetworkManager[2831]: <error> [1389390633.544433] [nm-manager-auth.c:87] pk_authority_get(): Failed to initialize PolicyKit: (23) Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ExecFailed: Failed to execute program /usr/lib/dbus-1.0/dbus-daemon-launch-helper: Success

Many thanks !

Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
