[solved] System lockup/high cpu usage

[Roux]

Hello, I’m a new unbraid user. I switched from freenas so thanks for barring with me.

 

cpu intensive tasks are locking up my system.

-sabnzbd unpacking, running the parity array, Plex transcodes if the file is too high of quality.

 

something I notice is alternating cpu threads are bouncing off 100%, is this normal?

 

I would really appreciate help looking at my logs and pointing me in the right direction.

You can try this and post that log after a crash.

My cpu usage was related to io backup.

the ca common problems identified 

“Share appdata set to cache-only, but files / folders exist on the array”

 

I ignored it thinking it wasn’t super important however once I stopped docker and invoked the mover my system is much faster doesn’t bounce off 100% usage on cores and is able to unpack compressed archives (sabnzbd) much faster, as well Plex streams don’t tax my system resources as much.

 

Hopefully this is helpful to someone else.
