Stability of the server after adding music

[firstWizball]

Describe the bug
I have a rather large collection of audiobooks and music split into separate directories.
I have noticed that since I have updated to the latest version that whenever I add a new music the server seems to scan for that new music straight away and takes a very long time to do this, and I cannot connect to the server to resolve it.

To Reproduce
Steps to reproduce the behavior:

1. not sure if this matters but I have a large music collection
2. Add an album to the collection
3. Server become unresponsive and nothing can connect.

Expected behavior
For a scan to happen at the time set mine is 0300 in the morning or when requested.

If I restart the server it comes back and works fine.

Can you share what plugins you've enabled? Automatic rescan requires an additional plugin to be installed. LMS by default would not trigger a scan when adding music to a folder.

Also what LMS version, containerised or not? What package? Any hints in server.log?

here is a image of the plugins I have active

Disable the AutoRescan plugin. That's what causing the automatic rescan.
