I am running icecast 2.4.3 on ubuntu 16.04, compiled from sources.

I have found out that if given XML config has invalid syntax, it outputs error but do not terminate the process. It is quite painful as it is not easily possible to check if service is running or not, as process exists.

/usr/bin/icecast -c /etc/icecast/icecast.xml
/etc/icecast/icecast.xml:1: parser error : Document is empty
FATAL: error parsing config file (/etc/icecast/icecast.xml)
XML config parsing error
