Like many, I had issues with sqlite database corruption on Unraid. I found while researching it that it had to do with file locks in the fuse file system unraid uses to merge disks. I found the best way to circumvent this is to use the cache disk for those databases and map them directly. My docker mappings now point to /mnt/cache/share instead of going /mnt/user/share. This solved the issue better than the 6.8.0rc5 fixes. This avoids the system in question completely and solved the stability issues for me.
Just another tech blag
