Random system crashes 6.8.3


Recommended Posts

Hi

I am new to Unraid and have been experiencing some random system hangups every other day. The machine seems to be running but I cannot access it from the web GUI and attempting to shut it down using the Power Off button doesn't do anything. Only thing left is to do a hard reboot which is obviously not good.

 

I have written the syslog to my USB and following are the last entries before the system got stuck:

I would really appreciate some help here. Thanks.
