Hello

 

My unRAID server seems to freeze up every once in awhile on it's own. I can't reach the webGUI or SSH into the server. I'm not sure what's going on but I have tried several things that have worked for other people such as changing docker network from macvlan to ipvlan. I also tried disabling c state in the bios (I have a Ryzen 9 processor). Any advice would be appreciated to resolve this issue.

Enable the syslog server and post that after a crash.

 

So the crash just happened again. One thing I noticed is when the server starts up and I start the array it takes forever for the first SSH to load my profile. Also same thing happens when I run a basic "ls". The single core is pegged for almost a full minute (see screenshots). After that it operates smoothly.

 

I attached syslog as well as diagnostics.

 

Thanks,

There's nothing relevant logged, CPU usage appears to be this:

 

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
18904 root      20   0 3572604 100656  18424 S  25.0   0.2   0:44.39 frigate.p+

 

O that's interesting. I'll check it out and see what's causing it.

Any recommendations for the freezing up issue? 

Not really, there's nothing relevant logged that I can see.

Is there a way to enable a more verbose log level for unraid? Nothing coming up from a few quick searches.

I also saw some references to max memory speed and max memory. Any thoughts on if my memory speed is set too high (using default settings) or if I have to much memory on the server (64 gigs).

So it just happened again (been happening about once every other week at this point). Checking the syslogs I think this might be memory related?

Look at the timestamp `Sep 11 15:13:17`

syslog-10.0.1.10.log

Multiple call traces logged, look more hardware related, try using just two RAM sticks, if the same try the other two, that will basically rule out a RAM problem, also note that there have been various reports of stability issues with Ryzen 7000, possibly just too new for the kernel.

Ahh that's unfortunate. Alright I'll test out the RAM sticks and see what's going on.

Also look for a BIOS update.

Sounds good - I'll check for BIOS version update next.
So I ran memtest86 and no errors after 2 passes. I did notice my memory by default is running at almost 4700 MHz. Could that be causing issues? Should I consider lowering the speed below the default? Reading up on the Ryzen 9 specs it looks like if I have 4 sticks I shouldn't be running faster than 3600 MHz.

I'll try reducing that and see things stabilize

DDR5 stock speed for that CPU is 4800MT/s IIRC.

SPD speed on the RAM is also 4800, and the diagnostics show you're running at 3600.

Cool, I should be good in terms of mem speed then. I did a bios update to latest today and I put a memory limit on my frigate containers in hopes that might help. I'll update here in a week or two if it doesn't happen again.

Update on this. I think my issue was my frigate container going crazy. Once I added a mem limit on it I haven't seen the crash since. So maybe that was the problem. I'll update again if I have another crash.
