Hello hive mind. 

 

Since last night my server keeps going offline, unreachable and unable to ping. I have had to power cycle it then it does the same within a few mins of starting up again. 

 

On a startup just (longest it has stayed online for) it has just come up in fix common as Machine Check Error and said i should post my diagnostics on here. 

 

I did have a little issue a few months ago where the cache was becoming unwriteable that turned out to be a ram issue which has since been replaced. Dont know if its connected just posting for more background. 

 

Anyhow, attached is my diagnostics.

Quick googling suggests that it might be power related  https://unix.stackexchange.com/questions/238454/hardware-error-in-syslog-after-gaming

Thanks I had a spare PSU kicking around so incase that was throwing a bit of a wobbly I changed it out but again over night I got another message saying machine check error events and woke up to the server being unreachable.
