Unraid disappearing randomly with no access

[danielaqz]

Hi, my unraid server started disappearing at random times, with no access through Web Gui, if i plug an screen to the pc it shows nothing.

Unraid is disappearing in the middle of the project while im accessing data from it.

I just power cycle the pc to get it working again and the parity check goes on. 

Temps are well, all fans running.

Recently i changed the switch for a lower power one, but it was working for at least 2 weeks before this started.. 

How can i Diagnose the machine?  (update, attached the syslog but it only shows info from the last reboot that was today.. also uploaded nas diagnostics)

Thx to all

You can also enable syslog mirror to flash then post that log after a crash.

Hi, the error happened again, only this time the nas came back without restarting.

Here is a part of the log. I was working fine until 13:10:02. I get up for Lunch and then came back to find it unresponsive, connected a keyboard and it came back to life, and i manage to enter the web Gui

Is this log enough ? or do I need extra information to pinpoint the issue?

You should zip the complete log from syslog server and post it and new diagnostics.
