Hi,

I seem to be getting frequent crashing on UNRAID 6.12.13 that eventually led to noticing a Flash Drive failure on my UNRAID but have since resolved that with a new USB and only copying over the config folder files. I seem to have been getting recent crashes getting applications triggering CPU stalls and was wondering if someone could help point me in the right direction. I ran a memtest with 2-3 passes and there didn't appear to be any errors. I also added a network card RTL8125B somewhat recently but haven't seen too many errors related to that. This is a sample from one of the crashes and was wondering if someone could point me in the right direction?

Uploaded Diagnostics and syslog, most recent crash had something related to a page fault but it appears it wasn't captured.

added version info

Remove the RTL8125B nic use terminal and console on machine. There are known issues with that nic driver and it requires some other edits to fix.

Thank you for posting diag will review here soon.

it is best to get a new flash drive and port over from a flash backup since the usb errors...  then boot the new flash and get the thing going before messing with the realtek nic and its issues.

typo - data

Not seeing much out of ordniay. i think it may be the nic...

The syslog contains entries related to RCU (Read-Copy-Update), but they appear to be standard initialization messages rather than directly indicating the "RCU preempt detected expedited stalls" problem. I'll refine the search for specific entries about expedited stalls, crashes, or page faults.

 

The syslog shows general RCU initialization messages, but it does not appear to contain the exact "RCU preempt detected expedited stalls" or "page fault" entries you mentioned.

 

This might indicate:

Incomplete Log Capture: The specific crash event may not have been fully logged before the system reset.

Intermittent Issue: The problem might occur sporadically, making it harder to capture.

 

Suggestions for Troubleshooting:

Enable Persistent Syslogs:

Configure Unraid to save logs to a remote syslog server or a non-volatile location to ensure crash events are recorded.

Network Card (RTL8125B) Suspicions:

Since the issue started after adding this card, consider:

Updating the driver for the RTL8125B.

Testing without the card to rule it out as the cause.

Thanks so much for the help, I'll give these a try and enable Persistent syslogs and try removing the NIC card for now and see if it continues to get any crashes. If it continues it'll likely crash again within the 1 to 4 days so I'll let you know if that resolves the issue and update this thread.

Seems to have been fairly stable after removing the RTL8125B so I suspect it was just the network card, thanks for all the help. I did disable a docker container for delugeVPN as well but I'll try turning it on and seeing how it goes for now before maybe retesting the NIC in 1-2 weeks.

there was a kernel update with another user.

remove the plugin if instaleld and update to lattest stable 6.12.14

I did upgrade the unraid version 4 days ago but didn't have the plugin installed previously when on 6.12.13. I will give that a try in a few days and reinstall the 2.5gb nic with the new 6.12.14 version to see if it resolves the issues.

Seems updating + disabling my deluge_vpn docker container resolved the issue. thanks for all the help! was able to reinstall the card and didn't have any issues for 8+ days now.
