Perl "Invalid argument error"

Hi ,

we have a issue in server, we are running a perl script to connect our clients, but we are not able to connect, every time we are getting the

"Invalid argument error"

Even i checked all the necessary perl modules are i installed in this server,

#create the listen socket
my $listen_socket = IO::Socket::INET->new(
                            LocalAddr => $MOBILLLLE_Proxy,
                            LocalPort => $MOBILLLLE_ProxyPort,
                            Listen    => 1,
                            Proto     => 'tcp',
                            Reuse     => 1)
or die "Can't create listening socket at $MOBILLLLE_ProxyPort: $!\n";

the above mention code i used in this script, every time when i try to connect. iam getting this output

Why iam getting this error.. Need your guidance to fix this issue.

netstat -a | grep 5005

I believe you will see the socket already in use.

100% iam sure, the socket is not already in use and i checked too..
