Hello Unraid Community,

 

I'm experiencing a persistent issue with my Unraid server that I'm hoping to get some insights on. I am running the latest version of unraid (6.12.6) as well as an updated bios (released Nov 10th)

 

Issue Description:

The server crashes specifically during Plex's sonic analysis process. This issue does not occur under other high-load scenarios or during general use. Initially, I suspected a CPU voltage issue since the crashes seemed to occur when a single core was under heavy load. I'll admit, I started with a negative curve optimizer offset in hopes I could get some extra performance. (I ran core cycler for 12 hours without issues on windows). After realizing this wasn't going to help.. I set everything to default except IMMO and AMD's virtualization settings in the bios. Not even enabling expo. Intriguingly, these crashes were not happening when the system was running Windows, suggesting it might be related to Unraid or the interaction between Unraid, Plex, and my hardware.

 

I've checked the /boot/logs directory, but there's nothing in there. However, going to Tools > System Logs does indeed show a log, but it only shows entries post-reboot, providing no clues about the crash.

 

Troubleshooting Steps Taken:

Monitored temperatures and power draw. (all seem fine, I don't think it is the power supply has it is fine under an all core load)

Ensured all software/bios are up to date.

The only thing I can think of now to do is to set a positive curve optimizer.. which.. is insane to me. (I set a positive of 5 on all cores just to see in the meantime.) This whole set up should be stable right out of the box. Is this how ryzen is? The craziest thing is I was running a negative 30 curve optimizer on every core in windows runing core cylcer. Anyway, I've also attached my diagnostics zip.

 

I'm reaching out to see if anyone has encountered a similar issue or might have insights into what could be causing these specific crashes during Plex's sonic analysis. Any suggestions or troubleshooting tips would be greatly appreciated.

 

Thank you in advance for your help!

Setup syslog server.

 Done, thank you. Had no idea that was a thing. I've only had unraid for about a month here.
