OK - This is a quick & dirty hack - I'm sure there are several more elegant
solutions... But it works.  NOTE: this is designed for a Shoutcast server.
You'd need to change the check=  lines to work with Icecast.  Couldn't find
an Icecast-specific copy, since I'm only using Shoutcast servers currently.

2 files:

#!/bin/bash
# Keepalive for liveice encoder
# bill at radioparadise.com
#

LOG=/usr/local/icecast/ka.log
SERVER=scastsrv2.shoutcast.com:8048
DIR=icecast
STREAM=RP128
STARTFILE=/usr/local/icecast/restart.128

echo "`date` - Keepalive started for $STREAM" >> $LOG
while [ 0 ]
do
check=`lynx -dump http://$SERVER/index.html  | grep -c "currently down"`
if [ $check = 1 ]
then
$STARTFILE
echo "`date` - $STREAM restarted" >> $LOG
sleep 10
check=`lynx -dump http://$SERVER/index.html  | grep -c "currently down"`
if [ $check = 1 ]
then
echo "`date` - Bummer. $STREAM on $SERVER is down" >> $LOG
else
echo "`date` - Yippee! $SERVER sez Stream Is Up!" >> $LOG
fi
# else
# echo "`date` - $STREAM on $SERVER OK"  >> $LOG
fi
sleep 20
done

[sample $STARTFILE]

#!/bin/bash

DIR=icecast

kill `/usr/local/icecast/ps xww | grep "$DIR/lame" | cut -c1-5` >/dev/null
kill `/usr/local/icecast/ps xww | grep "$DIR/liveice" | cut -c1-5`
>/dev/null

/usr/local/$DIR/liveice >/dev/null 2>/dev/null &
