Hello

 

my Unraid Server randomly crashed with a strange error message, i dont really understand.

The error happend around every 3-5 days, or like today, 2 times a day. I cant really reproduce it.

This error did not happend if i let the parity check running (for 23h) after a chrash.

 

The biggest problem is, that my complete Network is stop working at all. I cant even ping my router.

This happend on all >30 Devices in the Network till i hard reset the server. After reset the pings and the network is working again instantly.

 

So please help me to understand where the error is comming from and what i could do about it.

 

Thanks!

This might help with the crashing.

thanks for the tip.

I added rcu_nocbs=0-15 to the boot option. Hope this will help.
