#!/usr/bin/perl

use Expect;
use strict;

sub worker {
	my $exp = Expect->spawn("/usr/local/streambaby/streambaby");
	$exp->expect(undef, "java.io.IOException");
	print "     **** Killing *****\n";
	my $pid = `pgrep -f 'java.*streambaby.jar'`;
	chomp $pid;
	kill 9, $pid;
        return;
}

while(1) {
  worker();
}
