Hello. Liquidsoap 2.4.0 isn’t working properly either. There’s a known issue in Liquidsoap (see GitHub issues #4481 and #4670) where file descriptors aren’t properly released during error handling in the AutoDJ request processing chain. After some time, it reaches the descriptor limit and gets stuck. This is what version 2.4.2 fixes, but I totally agree that they should have tested it before releasing it, and this is quite serious. New version it's available already in testing branch.
