[6.5.3] Server hanging (kernel panic) monthly-ish

Farrukh · August 19, 2018

Hi,

I am trying to troubleshoot my server it seems to be hanging after about 30 to 45 days of flawless working. This issue initially started around 2017 September. I have tried various UNRAID updates and replaced hardware such as NIC, SATA Drive and GPU. I have looked at logs and stats during and after the 30 to 45 day before crash and found nothing out of the ordinary. For the most recent kernel panic, I have collected logs using plugin Fix Common Problem and attached the logs with this post. Here are the following things I have done to narrow this fault down:

1) Performed multiple memtest for 24+ hours without errors.

2) Performed xfs filesystem check with -nv (please find the results attached). I think the results are good but I could be wrong.

3) Performed btrfs scrub on my cache pool with no errors.

I am not sure at this point what is causing it to hang such unpredictably. Unfortunately I don't have the kernel panic screenshot for this particular instance since I am out of town. However, I have attached a couple from the last 2 failures. The screenshots are from March and May.

Unfortunately, I am out of town till August 30th. Hence, I wont have physical access to my server but I will be able to remotely collect and perform most diagnostic tasks.

Any help regarding this would be awesome
