Icecast might hang with 100% cpu use upon failed startup
I just ran into it again. It looks like it gets caught up in waiting for something.
Example output when trying to bind to inexistent IPv4 address:
$ /usr/bin/icecast -c /etc/icecast.xml [2015-01-08 05:21:48] EROR connection/connection_setup_sockets Could not create listener socket on port 8000 bind 203.0.113.23 [2015-01-08 05:21:48] EROR connection/connection_setup_sockets No listening sockets established Server startup failed. Exiting
"strace -f" doesn't produce any output after writing that last message.
