Hello, I've been dealing with intermittent OS crashes for the last 2-3 weeks. Tailscale containers become inaccessible, webui doesn't load locally, sign in on terminal directly from the unraid pc times out etc. After the first couple times this happened, I was able to diagnose it to a potential issue with the USB boot stick due to several "critical medium error, dev sda" messages while booting up.

I ordered a new stick, transferred my config and license over and all was good for about 2 weeks.

Now I'm dealing with the same issue again. This time, I set up a userscript I found on here to collect diagnostics every hour so I would have something fairly recent in case the server crashed again. I'm attaching those diagnostics to this post. Is there anything in there that would explain the frequent crashes?

Happy to provide more info if needed.

Data Volume monitor spams logs so maybe remove it during troubleshooting.

Nothing striking outside of all of Unraid, plugins and apps being woefully out of date included some deprecated ones, so probably gonna need to work on that first.

1. You're on a super old/outdated version of unraid. Consider updating. There have been loads of bugfixes from 7.0.0 RC to 7.3.2, I would start with the latest update your license supports.

2. Run unraid in safemode for an extended period with no plugins and see if crashes still occur.

3. Consider running a 24 hour minimum memtest from the boot menu to rule out bad ram

Thanks, I updated unraid to 7.3.2 and most of my docker containers and all my plug-ins as well. Will wait to see if that fixes things and if not, will try the memtest and safe mode. Will update on this thread, thanks!
