I've had my server running for a few years but cannot for the life of me figure this one out. I had a share named "Music" that I deleted a few months ago. I noticed that it would recreate itself after a few days. I would remove it (there were no files in it) and within a few days it would be recreated. Looking in my logs, I see the same pattern every time this happens.

There is always a Starting service... and a Starting Samba. I deleted this share on Jul 6 and it reappeared on the 7th, after my CA Backup ran.

Any ideas what is causing this to recreate?

You have a mapping to /mnt/user/Music on one of your docker containers

Yep, I bet that is it. Thanks for your help.
