Describe the bug The liquidsoap process hangs/deadlocks every now and then. I have not been able to find anything that causes it so I can't reproduce it, but it happens quite often.

To Reproduce I will work on a minimal script to try and reproduce the issue.

Version details

CentOS Stream 9
Version 2.1.0

Install method I installed liquidsoap from source and all the dependencies with opam.

I have made multiple stack traces to make sure that liquidsoap is deadlocked and it does look like it. Here's a sample of one of the stack traces. The issue also doesn't happen every time with the same track.
