Romain Beauxis commented on LS-532:
-----------------------------------
two issues here too :)
First, there was a missing set of changes in the current default branch which
triggered the "shutdown" exception issues (raised by ocaml-cry improperly using
Unix.shutdown, fixed in one of the missing commits). It should not be present
in default now.
Second is the fact that liquidsoap hangs instead of shutting down properly. I
think we have tried to fix this previsouly but apparently, there are still
cases where the threads do not terminate..
As for this issue, I do not know what to do. I can confirm that the exception
does not appear in current default, but liquidsoap will still hang if icecast
is not present.
The freeze seem to be caused by input.alsa.
I would propose to create a new issue for the freeze, _after_ testing it
against the branch that has fixes related to io/ operators and to close this
one..
