I appear to have a very intermittent (maybe once a month or longer) shutdown that I believe is related to this message in the log "Received signal 15; terminating."

 

Diag attached. 

unraid diag signal15.zip

Doubt that is the problem, enable the syslog server and post that after a shutdown, but the server shutting down by itself is usually a hardware issue (or bad power)

I had it setup to mirror to flash and attached current/previous.

syslog syslog-previous

I assume the syslog-previous ended with a crash?

Based on when syslog-previous ends (for date/time) it doesn't appear that the crash was actually captured. Not sure if there is a setting I have missed since it occured approx June 5 at 8pm est. 

Probably just there wasn't anything else logged from 5 to 8 AM, suggesting more a hardware issue, one thing you can try is to boot the server in safe mode with all docker containers/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one.

 

 

Hey did you figure out what was the issue? Or what hardware has caused this? I am having the same issue.

Syslog previous is almost empty, but make sure this has been taken care of:

I did not, however I suspect the UPS (battery backup) may have been the issue.

Thanks I will look to see if that can help. I plan to pull the system to check the AIO, memory, and the power supply. I am handicap so I will  have to wait for my wife to help me pull the system

I plan to pull the system to check the AIO, memory, and the power supply and check each just to be sure

I am going to have  to agree with the UPS diagnosis you made. We pulled my server and placed it on a cart which ment it was disconnected from the UPS. It has been up and running since this morning without issue. I wonder if something changed in UPS handling during the last unraid update

At least in my case I believe the UPS is defective, switching to a different UPS has been stable thus far although with mine the issue was very intermittent (could have upwards of 30 days uptime before an issue).
