I looked at your server socket. There's a problem with IO::Select's can_read. If there's no timeout given, or if it contains a registered handler, can_read will block. Here's how I would handle the socket:
#!/usr/bin/perl select(STDERR); $| = 1; select(STDOUT); $| = 1; use autodie; use strictures 1; use IO::Socket; use IO::Select; use Log::Log4perl; my $sock = new IO::Socket::INET( LocalAddr => 'www.example.com', LocalPort => 9000, Listen => 128, Reuse => 1, Blocking => 0, Proto => 'tcp', ); our $selSock = new IO::Select($sock); while( my(@ready) = $selSock->can_read(10) ) { use strict qw/refs/; use warnings FATAL => 'syntax'; foreach $_ (@ready) { if ($_ == $sock) { my $logger; my $clientPool; $logger->info("Base socket is " . $sock); $logger->info("Adding new socket"); my $newSock = $sock->accept or die; $logger->info("Added new socket " . $newSock); $selSock->add($newSock); my $fd = $selSock->fileno($newSock); my $address = inet_ntoa($newSock->peeraddr); my @values = ($fd, $address); if ($clientPool->queueJob( queueValues => \@values)) { $logger->error( "Failed to queue client connection" ); my $trash = <$newSock>; $trash->send($newSock, "** ENQUEUE_FAILED **", 0); $trash->send($newSock, "** ZERO_BYTES_LEFT **", 0); $selSock->remove($trash); $newSock = undef; sleep 1; exit; } } } }
