Looks like it ran for 3 hours before hanging.  This time the last message was:

Feb  6 11:01:02 medon systemd: Removed slice user-0.slice.
Feb  6 11:01:02 medon systemd: Stopping user-0.slice.


Someone please chime in on how to upgrade the kernel. It has not been pushed to the kernel repo,,,

My server hung yesterday.  I did not notice it; at this stage in the 
game, I should be much more aware...

I looked into /var/log/messages and my last entry was:

Feb  5 15:03:46 medon kernel: conntrack: generic helper won't handle 
protocol 47
. Please consider loading the specific helper module.

So I don't know if someone knocked me over with a GRE based attack, if 
the drive is bad, if the board is bad, or the OS has a problem.

So simple things to start with.  I see an earlier GRE warning in messages:

Feb  5 03:29:49 medon kernel: conntrack: generic helper won't handle 
protocol 47. Please consider loading the specific helper module.

So it is probably not a stack problem with attacking GRE bots.  BTW, is 
there some 'easy' way to just block these?

As to the drive:  Is there some way to run a SMART? check on the drive?

Can't really tell too well if it is a board problem other than to watch 
more closely to see how things go, is there anywhere else I should look 
to find the problem?

thanks
