I have started several threads since update 7.2. I really don't know what this minor update did to my system, but for weeks now it's driving me crazy.

So lately I got the problem that I can not stop or restart the server without crashing. It is always stuck on "Retry unmounting disk share". I have no idea why. The logs won't tell me. I guess I changed one setting somewhere, and since then, I've this problem. The previous solutions from other threads didn't work. I realized that the Docker daemon is already stopped, so that is not the reason.

Let's get back to my Docker problem. Sometimes I restart the server, and Docker container won't find each other via name. They are in the same custom network but cannot be resolved. Like, for example, wordpress-db:3306. When I restart Docker via /etc/rc.d/rc.docker restart there is a good chance that it is fixed out of nowhere. But not always. Sometimes I restart several times, and it does not help.

I have Docker installed on my cache drive, formatted with ZFS. So I installed Docker as folder as recommended. I also reinstalled Docker more than once. For a while it works but after one restart I got my problems back. I don't know what to do anymore. If the server is in a state where nearly everything works, I'm so scared to do anything.

After one server restart, it was like this for Authentik or Nextcloud:

INF | event=PostgreSQL connection failed, retrying... (connection failed: connection to server at "172.19.0.45", port 5432 failed: server closed the connection unexpectedly
	This probably means the server terminated abnormally
	before or while processing the request.) logger=authentik.lib.config timestamp=1768564550.3915546 

So basically, the URL is correctly resolved because the IP is correct, but still, no connection can be created. My logs are attached. Also, my diagnostics. I already tried Docker with macvlan instead of ipvlan, but I think it made it even worse.

Please help me. I mean, for sure, I run 150 containers and more, but before the update, it worked without any problems.

Bump...

is there anybody with this problem? My system is unusable like this...

I'm also thinking about a hardware issue now, but not sure if this makes any sense. I mean, how bad and wrong could my Docker setup be? Could my internet router also be a reason?

What I found out is that the "Retry unmounting disk share" while shutting down has nothing to do with Docker. It was deactivated. I could not even find any process when the problem occurred. I tried the command ps -ef | grep /mnt/user in several variants with disk1, disk2, and so on. It always just returned one entry with root, which was the terminal. So no clue about this, too.

I'm even willing to gift someone who helps and finds the reason and solution some money. I don't know what to do anymore, and I love Unraid and even propose it to everybody, and now it literally breaks me.

To try and debug this you can disable Docker and VM service and reboot in safe mode, start the array and see if it stops, if yes, retest again after booting in normal mode to rule out a plugin issue, leave the services still disabled, if still OK enable one of the services and retest, then the other, note that if the issue happens with the docker service enabled only, you may need to try enabling one or a few containers at a time to find the culprit.

I'm honestly scared of restarting now. Docker works fine again now because I deleted the Docker directory, created my custom Docker network again, and installed the apps, and knocking on wood, it works (FOR NOW).

There is a high probability that it will start to break again when I restart. If I have free time and I'm able to take that pain again, I will try what you said.
