My unraid server has experienced 2 kernel panics within the past day. I have not made any recent changes to the system. A screenshot of the console reveals that an invalid opcode 'PREEMPT SMP NOPTI' may have triggered the panic. I am attaching the screenshot in case this info helps. I am running Unraid 7.2.4, and wondering whether updating to the latest version might help. Thanks!

Nothing logged in syslog, I would just reboot and monitor for any abnormalities. You could also try updating unraid to a newer version with a different kernel version.

Thanks for your help. Currently running a couple cycles of memtest, but no errors so far.

Question: I lose all my dockers when unraid crashes, but they can be easily reinstalled with their data preserved. Should I reinstall my dockers prior to updating unraid to avoid data loss?

Thanks again for your assistance!

Say what now? That is not normal...

can you start the array and post new diagnostics?

After running memtest (no errors after 2 passes) and starting the array, the dockers were present. After the earlier crash today (and one several days ago) they were missing and I needed to reinstall all of them. Weird...

Here is the updated diagnostics. TIA!

Make sure this has been taken care off, even if it wasn't an issue before https://forums.unraid.net/topic/46802-faq-for-unraid-v6/page/2/#findComment-819173

Also enable the syslog server and post that after the next crash.
