Since this is embedded system, there's no GUI, you can just view message outputs from console.(BUT we do 
have 2 login sessions, 1 is for GUI, don't ask me why, someone else did it)
We use networkmanager to manager the 2 ethernet ports. Most of the time it's fine.0Once a while no network 
connection, and turned out to be networkmanager process has died.Pls note this could happen during 
weekends, no one is touching the board, our application should has nothing to with it.
Also Not sure if related, but someone's board displays this,
** (process:31111): WARNING **: Could not initialize NMClient /org/freedesktop/NetworkManager: Did not 
receive a reply. 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.
Error: nmcli ( and NetworkManager (unknown) versions don't match. Force execution using --nocheck, 
but the results are unpredictable.
The funny thing is, our NetworkManager is 0.9.4 from "--version".Where should i get started on this pls ?   

Are you able to get a crash trace from NetworkManager?  One way to do
this would be to run NetworkManager under 'gdb' if possible, and wait
until it fails, then do a "backtrace" command to see where NM crashed.
Ideally the board would also have NetworkManager build with debug
symbols too.

Would you be able to run NM under gdb and get a backtrace?

Would you also be able to get some syslog 'daemon' facility output as
well?  (usually /var/log/messages or /var/log/NetworkManager.log
or /var/log/daemon.log)
