I am running 4.5.6 and am having a strange issue right now.  Last night, I could not access any of my shares, could not access the Web GUI, and could not telnet to my server.  I have a console on the box, but it was not responsive.  So...  I had to cycle the power.  On power-up the server started a parity check and before I called it a day I checked and no errors were found.

 

Now, the next day, I can access my shares but still cannot telnet or access the Web GUI or console.

 

The attached picture is what I see on my console last night and right now.  Might anyone have a clue from this pic what might be going on?  I have no access to the syslog right now.

I'd perform a memory check as the first step.  It is possible you have had two of the kernel-oops that were fixed in the 4.6 version of unraid, but a memory strip that is defective or incorrectly set with the wrong timing, voltage or clock speed could cause all kinds of the errors you are seeing.    Some BIOS get it right, some get it very wrong, especially with premium RAM.
