Losing Network Connection?

Featured Replies

I have been random losing gui access to my tower on my network and i am unable to determine if the system is running normal. When i log into the system local i try running diagnostics in the terminal window but it just hangs there. i also try a ping to my router @192.168.1.1 and no response. I run the powerdown -r command which hangs at forcing shutdown. Any other commands i can use to pull data to see what is causing this issue

Try this.

I started a syslog server on my windows server and sending to the flash(probably stop this soon). So far no issue with losing network. Anything i should look for in the syslogs? I see some kernel warning logs

Post the complete syslog when you lose it again, those call traces look network related.

Actually at home now in front of the system. Tried just a powerdown. Showing forcing shutdown now but doesn't actually shutdown unless i power down the sever manually

Lots of call traces, first ones seem to be xfs related, so start by running a filesystem check on all xfs filesystems:

 

xfs_repair -v /dev/mdX

 

Same for cache if xfs, also a good idea to run memtest.

All of these are ran with array stopped?
