Lost async page write

I have been getting errors off and on for the past few weeks when transferring files from another server onto this unRAID server. I have noticed this happens with any server I have tried to connect with.

I only seem to get this error when i have dockers enabled. I notice my deluge daemon has 0.0kbs and SMB cant access files or directories. Sometimes the web ui is slow and unresponsive too. Sometimes my file transfer eventually gets a network error in teracopy.

Generally when this error happens I dont get much in the logs. But I noticed this time when i was transferring files, running dockers (mainly deluge and plex) and preclearing 2 new drives I got a lot of errors in the logs. I also noticed one of the drives I was preclearing disappearing from unassigned devices. This is just a snippet of my errors. Any help at all is appreciated.
