Only fix I keep coming upon is to update libtalloc2. https://answers.launchpad.net/ubuntu/+question/291448 I'm reading that unRAID runs on memory and everything is packed into bzimage. I'm not sure what to do here at this point. Downgrade back to a working version?

Just upgraded to 6.3.4 and now cannot access any shares, turned on debugging and see similar to you:

Have you managed to fix this ?

Please try 6.3.5 and see if error persists.

Seems to fix it thanks
