Every now and again my unraid server locks up. I am not sure why. It is always under load of some kind so I doubt its sleep states. It can be fine for 8 months and then lock up twice in one month.

I set up a remote an syslog server in order to pull logs out as it freezes, I have attached these logs (i truncated the kernal.log as it was 500mb in size) and my diagnostics. I am pretty lost on this one.

Various out of memory errors, limit RAM setting for the various services.

Hi JorgeB. Thanks for your reply.

All my docker services have memory limits and I have never seen my instance memory go over 87% usage, of 64GB of ram.
Any particular service that needs more attention?

Something is still causing the errors, so try and reduce some more, or try running just some services at a time to try and find the culprit.

I tracked down the image ID inside docker and found that it is being killed all the time for oom, it had a memory limit of 150Mb and was going over that limit leading it to be killed. I checked the recent logs and it has been killed since the major lock up but not caused another lockup. I am not confident that it is directly causing my server to look up. I have however increased its ram limit to 350Mb

I had this similarly happen last year, it was random about every 3 months. I ended up doing an MEMTEST, and found a single stick of ram went bad, replaced it and the server has been running for 10 months, no issues.

Hey Donovan, thats possible. I will give that a try thank you.
