My machine unexpectedly crash for 3 times for past 3 days

Featured Replies

I don't know why and first my zfs pool showing one of the drive has too many error, I tried "zpool repair" couple time and it always resulted too many error, today I replaced the drive and resilver took about 10hours, 4 hours later, my machine was unaccessible again. I have to restart the machine again. Now it work again.

anybody able to find out what's the problem? Hardware? software?

Thanks in advance

I'm still crash somehow.

From the log I have this

Aug 30 13:07:00 Night kernel: br-5362b0a0424e: port 3(vethd82bb6c) entered blocking state

Aug 30 13:07:00 Night kernel: br-5362b0a0424e: port 3(vethd82bb6c) entered forwarding state

What does this mean?

I have attached the syslog.

What I have done so far.

-updated to latest BIOS

-change Power Supply Idle Control to "typical current idle"

-remove GPU

-run 24hrs memtest with 5 pass no error

-replaced ethernet cable

-start unRAID with safe mode without plugin

-docker custom network type from "macvlan" to "ipvlan"

-disable docker disable VM

-removed all docker reinstall some of the docker.

-change ethernet port(my machine has 2 ethernet port)

-Replace USB Flash

So far, I haven't pass 30hours mark. It always freeze before 24hrs mark.

Next I'm going to

-run another memtest for 48hrs to make sure isn't hardware related issue.

any other suggestions on what could be the issue?

These are normal when a Docker container starts/restarts; it's only an issue if it keeps happening 24/7. In that case, it generally means there's a container constantly restarting.

I don't see anything relevant logged, suggesting more of a hardware issue, one thing you can try is to boot the server in safe mode with all docker containers/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, including the individual docker containers.

Does memtest same as run as a basic NAS for test hardware issue?

I am currently running memtest ongoing 21hours, no crash yet.. Previously I ran it for 25hrs and no crash either.

Memtest only use some hardware? like hard drive will not get connect / supply power?

You can use memtest to test the RAM, but keep in mind that memtest is only definitive if it finds errors, if you have multiple sticks try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.
