Hello everyone and thank you in advance for your assistance! I installed unraid 6.3.5 trial two weeks ago and love it with the exception of the instability issue I am facing on my machine. Sporadically (sometimes every 12 hours sometimes every 24 hours) my install will suddenly become unresponsive. I can still ping the IP of my server but cannot access it via web UI, cannot SSH or Telnet, and cannot login to do a safe reboot at console either. (System still shows the console login screen but does not respond to any input even though keyboard still shows as connected.)

 

I have been legitimately trying to get log files for this issue for the past week and a half and so far have not been successful and have had to do way too many hard reboots for my liking. 

 

• I have run memtest for 3 passes without error.
• All voltages and clock speeds have been set to fixed numbers in bios settings instead of auto. 
• I have since attached a UPS to the system as I was thinking it may have been a power issue. (No luck unfortunately.)

 

I am starting to think that the issue is being caused by my USB drive. my system specs are below. has anyone else had trouble with USB 3.0 drives in USB 3.0 ports? or is my flash drive just going bad? am I on the right track or way off base in my troubleshooting? Any thoughts or ideas would be greatly appreciated!

There are know stability issues with Ryzen and unRAID releases prior to v6.4rc7, upgrade to latest rc:

 

 

 

Thanks Johnnie - I will give this a try tonight and update with the results.

I have updated to version 6.4.0-rc8q and it's been running for 4 hours so far without issue. I will let it run overnight and report back.

Unless things have changed for the Ryzen processors or in 6.4, it is also generally recommended to not use USB3 for your boot drive - USB3 capable sticks are OK, though. Little enough happens on the flash drive after boot that it's no real loss.

Thanks @FreeMan I will try swapping to a USB 2.0 port if the issue persists after the 6.4 update. 

The stability issue seems to be resolved now! Thanks everyone for the input! The version update was all that was needed.
