I'd recommend that you start out working with one thread, then two, three, etc. until you get a feel for threads. I couldn't replicate your error, but then I didn't use threads the same as you. Here's a simplified script to check the number of threads enqueued:
#!/usr/bin/perl -l BEGIN { $| = 1; $^W = 1; } use strict; use warnings; use threads; use Thread::Queue; use LWP::UserAgent; use constant THREADS => 3; my(@urls) = ( 'http://search.cpan.org', 'http://www.perl.org', 'http://www.cpan.org', ); my $workq = Thread::Queue->new; my $thr = threads->create( sub { while(defined(my $url = $workq->dequeue)) { do { my $ua = LWP::UserAgent->new; foreach my $url (@urls) { my $response = $ua->get($url); if ($response->is_success) { print $response->decoded_content; } else { die $response->status_line; } } }; } }); $workq->enqueue($urls[0], $urls[1], $urls[2]); my $num_working = $workq->pending(); print $num_working; $workq->end(); $thr->detach(); undef $thr;
