Perhaps something like this could be used instead? This has not been
thoroughly tested, so consider it a blueprint :-)
Idea: Initially, signal only the parent process with the INT signal to
let it gracefully end all its child-processes and itself. If the parent
process does not terminate within some threshold of time, something is
hanging and we basically perform a killall -TERM on the remaining processes.
pkill -INT -P 1 `basename $DAEMON`
TIMEOUT=30
while pgrep -P 1 `basename $DAEMON` >/dev/null && test "$TIMEOUT"
-gt "0"; do
TIMEOUT=$((TIMEOUT-1))
sleep 1;
done
if test "$TIMEOUT" -eq "0"; then
pkill -TERM `basename $DAEMON`
fi
Food for thought...
