Network just dies

[Patrik Hansson]

Hi
Having some trouble with my FreeNAS 11-U4.
Networks just stops working, if i go to the console the server seems fine otherwise.
Where do i start looking? Which log files do i check?
Can i test to revert to U3 (meaning does it just boot older version with same config as current) and see if that fixes the problem? Wasn't there before U4.

Check /var/log/messages for any possible issues. Have you also verified that your NIC, cable, switch and/or router are also good?

messages don't give much.
Have changed switch before and now also cable. Will see if that helped.

Code:

Nope, it seems to have died again at night. Will look at replacing the nic if no one else has any suggestions.

Hardware specs? Read the forum rules and following them please.

There is a thread and a related bug report ("Closed: Cannot reproduce") with a very similar traceback from FreeNAS 11.0-RC3. I'm not sure if the information given there will help ("As soon as I took off VPN internet, the emails started coming through and no crashes.").

Ah, that looks like my issue.
Not using vpn though but will check this out.

@SweetAndLow Yea, sry about that. Will fix when i get my system back up.

 

[Patrik Hansson]

Ok, so I reverted to U3 yesterday and this morning the system was still up.

 

[Patrik Hansson]

Keeping the monolog going..
Died during the night again on U3.
Trying to get hold of new nic to try.

Disabled email by setting a dummy ip as smtp...haven't had a problem with the network since then.
