Hi General Support

 

I have an Unraid Pro system that has been running for around 3 years quite happily.  Over the last few months I have been experiencing semi regular/regular I guess crashes.  The system disappears for 5-10 minutes and when it comes back reports an unclean shutdown, which then triggers a parity check.

 

There have been no hardware changes since I built it 3 years ago and I have a bunch of Docker containers running (27) but no VMs.

 

I'd like it not to do this (crash) so I'd appreciate any help that anyone can give; I've attached diagnostics logs taken right after the most recent crash.

 

Many thanks, Barrie

Start your own thread with a complete description of your problem and your diagnostics.

Haven't looked at them yet, but they can't tell us anything that happened before reboot.

 

Setup syslog server

Setup syslog server

Thanks, I've done that and will update once it happens next.

It's happened again and here is the syslog.  The first entry in the now current syslog (Tools > System Log) is at 04:29:20 so it happened just before that I guess.

syslog-192.168.1.5.log

Should I post the syslog in a new topic?

No

 

Nothing obvious

 

Have you done memtest recently?

I have never run memtest - would you suggest that as my next course of action?

 

If so should I be using https://www.memtest.org/ or https://www.memtest86.com/?  (my system boots in UEFI mode)

The memtest results are in; 12 hours of testing found 0 memory errors.  Report attached.

Is there anything else that I (the OP) should check?

There's nothing relevant logged in the persistent syslog, this usually suggests a hardware problem, one thing you can try is to boot the server in safe mode with all docker/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one.

Sorry for the hijack. I have split that other user into their own thread.

Since my last post I've had my server running on my bench, where I moved it to perform the memory test on Sunday, 4 days ago.

 

It normally lives in an out of the way place on a UPS and with only a network connection.

 

On my bench it is not using the UPS and has a keyboard, mouse, monitor and network plugged in.  It is also started in GUI mode.

 

It has now been up for 3 days 10 hours 22 minutes, which it has not been doing for months.

 

Could there be anything involving the UPS that might make it crash & restart without anything useful being logged?

It's possible.

My server has been 100% stable now for over 2 weeks so I no longer have a problem.  It has been back in its normal location for almost 5 days, with only a network and UPS connected.  I'll mark this as the solution as I don't know what the actual problem was.

 

Thanks for the help fault finding.  I have a better idea of where to look for issues now.
