You have had the correct file rights and this message already occurs in error.log? The icecast.xml is accepted without problems during regular start? Your icecast runs stable? Solution: Maybe you have chrooted and the icecast process now can not access to the icecast.xml you have had provided via command line.
Stopping: If isamkmpd is running in the foreground, ctrl+c does not flush existing connections (SAD’s). Do a little ipsecctl -F kill -9 kills only the daemon, the connections stay alive. Use kill -TERM instead. Or use the isakmpd FIFO user interface: echo ‘Q’ > /var/run/isakmpd.fifo Reloading: kill -HUP or echo ‘R’ > /var/run/isakmpd.fifo
