Can't resart liquidsoap without killing process manually - linux

Question

I am currently running Liquidsoap on Ubuntu 14.4, streaming to Icecast, hosted on the same box.
My setup is running correctly, however when running sudo service liquidsoap restart, I get the following error:
fatal error exception unix.unix_error(50, "bind", "" )
In order to restart liquid soap, I need to kill the process or reboot.
It then runs correctly. Until I need to restart for whatever reason.
As a side note, liquidsoap created a user and group called liquidsoap, however I am running sudo commands via another user I created.
Does anyone have any ideas?

Fixed by enabling pid file creation.

None of mentioned solutions solved my issue. I had to fix it recently by setting proper ownership and permissions right after starting daemons. After killing the processes and restarting, further restarts work fine.
start-stop-daemon --start --quiet --pidfile $rundir/${liq%.liq}.pid \
--chuid $user:$group --exec $liquidsoap -- -d $confdir/$liq && sleep 1 && chmod 600 $rundir/${liq%.liq}.pid && chown root:root $rundir/${liq%.liq}.pid
