The Odd Angry Hang or Restart


Recommended Posts

My UnRAID server is for the most part quite solid, but I do get the occasional restart or server hang.  Nothing has ever popped up in the syslog before the event, and as it's headless I've never seen what the screen is showing.  I can go a couple of months without anything or I can have a few in a short space of time.

 

Yesterday I had a lockup where a cold restart was needed to get back.  I just had a server reboot.  Because it's not constant, or can be triggered, I've refrained from trial by elimination and starting it without plugins or dockers and slowly adding until I get an event.  It would take too long and render my server useless for what I need it for.  So for now it while just be something to deal with but I've attached my diagnostics in case someone has the desire to wade through and see if there's anything obvious amiss.  There's a few errors in the syslog at every startup but I've always ignored those without knowing what they mean.

 

TIA to anyone that has the time to have a look.

Diags after rebooting aren't much help, you can try this:

I do run syslog onto a server as well as duplicate it on flash. This was in the attempt to capture some info before the boot/hang. There is nothing before a hang or reboot that I see. 

 

Let me grab the current syslog and anonymise it a bit and I can attach. I mistakenly thought the Diags would grab the whole syslog.

Here's the syslog entries leading up to a reboot or hang.  As you can see there is nothing in the logs pointing to why the server has hung or rebooted itself.  Happy to send through the whole syslog if that helps.
