Issue:

Whenever my Cache drive has less than 64GB of free space (total amount of ECC Ram I have), the system goes haywire. GUI is unresponsive. I get the following error since the /user folder disappears:

Transport endpoint is not connected

 

Mover is run every hour to keep the Cache drive as empty as possible. I have a share IncomingMedia  that is set to use the Cache and have a MEGAdownloader program on my physical Mac mapped to the share as the download location.

 

My process for getting media and transporting it to unRAID:

1) Select files to start auto downloading on the Mac

2) Files start to save on unRAID IncomingMedia share from Mac

3) After files have downloaded, I move them from a "Downloading" folder to a "Completed" folder (no moving actually happens from Cache, since both folders are under IncomingMedia)

4) I then do a move via Midnight Commander (MC) in terminal to my PlexMedia share (also set to use Cache)

 

Diagnostics are attached.

You've got CA Auto Turbo mode sitting in debug mode which doesn't nothing other than needlessly spam your logs.  There's also a ton of page allocation stalls / out of memory issues, that may be contributing.

 

See if this helps https://lime-technology.com/forums/topic/58855-regular-out-of-memory-problems/?tab=comments#comment-577424

 

I've actually disabled the debug mode for CA Auto Turbo as of yesterday, before the most recent crash.

 

EDIT: I followed your link and updated the items suggested. We'll see if it is still showing more OOM errors today!
