Random reboot of server. Previously running for months no issues.

[Risto Randala]

Hi

 

Hoping to get some help. Server suddenly started rebooting out of nowhere. First thoughts were faulty ram. Swapped them out. Then thought faulty PSU. Swapped it out. Server runs 16 hours up to 1 day and suddenly i see vm s are rebooted so i also notice the whole server has rebooted. Sometimes it takes 1 hour and 3 hours. Its totally random. I dont know what happend. Been using unraid for years and help would be appreciated. I have attached diagnostic logs if this helps to narrow it down. Mainboard and all the components are 1 year couple of months old so quite new setup.

 

Can anyone please help solve mystery of my reboots. 

 

Thanks in advanced.

You should enable the syslog server so that we can get a syslog covering the period up to the reboot.    By default the RAM copy of the syslog included the diagnostics restarts afresh on every boot.

did that adding log

I kind of enabled it but just before another reboot so i think i will leave it on to collect more logs and come back here with a larger log to look at. Sorry my bad. Had this idea only as today to turn it on.

We need the log after a reboot.

Today it happend again but this time while i was looking at the log it rebooted again but this time system didnt come up so i had to reset the server. After that unraid booted up and looks like its running god knows for how long this time. Attached is the log should contain multiple reboot cycles.

syslog-10.10.10.245.log

There's nothing relevant logged, and that's not unexpected, if the server is really rebooting, instead of crashing or hanging, it suggests a hardware issue, and those usually don't leave anything logged, try running memtest and/or a different PSU if available.

At the first post i mentioned doing it. First swapped out memory modules and then also swapped out PSU. Still random reboot at random interval and times a day.

Could be board or CPU for example.

Unfortunetly it was the CPU I had same socket AM Ryzen processor and once replaced the processor no issues no more. Totally working again no reboot. Swapped CPU back and in 6 hours a reboot. So got resolved but didnt like the outcome.

 

For reference the cpu that wa F***ed up was AMD Ryzen 7 5700G with Radeon Graphics @ 3800 MHz The price and power was great i hope it was a fluke on AMD line cause bought exact same new one and now running with no problem again. For some reason the warranty had just expired like a month or two before it failed.  (Usage 2.3 years)
