I wrote the following code to listen to a TCP port on a device and simply log it's output. It seems to work fine for about 10-20 hours, but somewhere along the line it just stops, and I can't figure out why. I put the socket timeout all the way up to 604800 sec (7 Days) hoping that it would help, but no luck. I have been using a script to restart the process every hour so it doesn't die on me anymore, but I would like it to just work. Any ideas?

use Net::Telnet();
use strict;

my ($host, $port, $socket, $line, $filename);
$host = $ARGV[0];
$port = $ARGV[1];
$filename = $ARGV[2];
$socket = new Net::Telnet (Telnetmode => 0,Timeout => 604800);
$socket->open(Host => $host,Port => $port);
for(;;){
        $line = $socket->getline;
        open(LOGFILE, ">>$filename");
        print LOGFILE $line;
        close(LOGFILE);
}
exit 0;
