FCP is telling me that I am having a hardware error due to Machine Check Events detected on your server

 

I downloaded the diag and looked at the syslog.  I see the MCE's but I can't make out heads nor tails of what it means.  Any help?

You have a hardware fault that's showing up early in the boot sequence while the multiple cores of your CPU are being initialised.

 

I'd run memcheck (select it from the boot menu or download the newer version and install on its own, separate USB flash and boot from that) for a good long time (48 hours, say) first. If it passes consider reseating the CPU and checking for bent pins. You can install mcelog using the Nerd Pack plugin.

 

Other worthwhile things you can do include checking for a newer BIOS and updating to unRAID 6.5.3.

I have mcelog installed from Nerd Pack.  I have been running it for a while.

 

I can try the memtrest but this is a pretty heavy server running a Win 10 VM that I game with as well as running many dockers including Plex which transcodes.  I would think that if I had a stability issue or a memory issue I would have run in to it by now no?

Upgrading to 6.5.3 may also help as it will include later microcode updates than your 6.5.0

 

Thanks for the heads up @Squid.  I didn't realize there was a new version out.  I do not like the new update feature of unRAID.  It used to be easy to tell if there was a new version, now I find I never get notified or can see it.

 

I will see if the issues continue with the new version.

You just need to go to Settings - Notification settings, enable Check for OS updates (on whatever schedule you want), and set up your email or notification agent
