Hello I am running Unraid 6.9.2 Plus and have 6 drives installed, 4 connected directly to the motherboard and 2 connected to a SAS to SATA card. A while back I had an unfortunate power outage when I wasn't home and box was not connected to a UPS. I mention this as this is the only odd event I recall happening, rest of the time everything was smooth with Unraid. 

 

Now randomly (sometimes in as little as a day upto 10 days) the server will become unresponsive, I am unable to do a normal shutdown/reboot or take the array offline, the only way is to force a reboot but powering down the machine by holding down the power button. When I look at my dashboard I notice that several cores/threads are stuck at 100% 

 

 

 

Thanks,

Jon

You should post your diagnostics when cores are pegged

Hello Squid, 

 

thanks for the feedback I will enable to mirror to flash function and post the sys log as soon as it happens again. 

 

that said I just encountered another issue. this has only been a few hours since I did the hard reboot this morning, but just now when I checked I now get the following error as if I do not have a license but I do ? Could it be my flash drive got killed during the power outage ? 

 

So apparently I already had the mirror to flash option enabled, but when I try to upload the log file I get following error now ?

Try in a different browser

OK for some reason it seems the only way to get it uploaded is to zip the file. 

 

Attached is the log file, thanks in advance!

Does it still happen if you disable s3sleep?

While this is not optimal I will try disabling S3 sleep all together to see if it makes any difference. 

 

thanks!

OK so even with the sleep disabled the problem still presists

It seems like the USB drive has failed ? Found this at the start of the errors...

Recommendations on how to proceed ? I have lost webgui now  

I got a new drive, copied the files from the old flash to the new and did a hardboot but still no network connectivity and hence no GUI. 

Any help ?
