Server keeps Going down

[NRF19]

Every now and again my server just stops running, it is still on so not a hardware fault, basically i cannot access anything from the main web interface to opening a telnet session to it or accessing any of the shares, however i can access unmenu which is where i've managed to grab my system log from.

 

Its been doing this for a while now, once every week, top combat it previously I've just installed a back-up of my usb again and again but its something that keeps working its way back, anyway attached is my syslog hopefully you can help me.

 

Thanks

Disable all add ons and see if the problem keeps happening.
