Where can I find the logs to inspect?  I copied the flash drive prior to booting but do not see a current syslog.

logs are in ram (/var/log/syslog)

 

Easiest to run a diagnostics, but after a reboot the log is lost.

 

If the crash is recurrent on a regular basis, then Fix Common Problems plugin in troubleshooting mode would be the best way to grab the logs

My system crashed again and I was running the Fix Common Problems in troubleshooting mode.  Nothing jumps out at me, could some else take a look?

I found the below in your log, not sure if this would cause your problem, the only other thing I saw in your diagnostic was some warnings in your libvirt.txt file. Although others with more knowledge of dockers and VM's will chime in, I would check your docker and VM set ups, starting with the one using IP address 218.87.108.154 and if they look good to you, shut down all dockers and VMS, check for stability then introduce one at a time until you find the one causing the instability.

These are probably hack attempts.

 

pepper, is your server on the internet?

Is this server exposed to the Internet?  I would suggest that you google  'where is 218.87.109.154' as it is somewhere in China.  The unRAID server should never be exposed  directly to the internet as it is not hardened to resist hacking attacks which will occur within minutes of direct exposure! 

there is one ssh port open and there are numerous attempts but I haven't seen any successful connections that aren't me.  The deny script works pretty good and I have one ip address in the allow list.
