If no other threads are dying then its certainly something code specific in the subroutine for that thread. Have you tried running your "picker" code without threads? i.e. single threaded mode? Instead of pushing something onto the Queue after accepting a socket connection just call the picker subroutine. If it dies in the main thread you should have an easier time debugging it.

Also, some code to catch __DIE__ could be really useful. Try this:

$SIG{__DIE__} = \&sig_die;

sub sig_die{
    my ($msg) = @_;
    # Do nothing if called from inside an eval block.
    die @_ if $^S;
    stack_trace();
}
sub stack_trace(){
    use File::Basename;
    print STDERR "\n-------Begin Stack Trace-----------\n";
    my $i = 0;
    while(my ($package, $filename, $line,$sub )  = caller($i++)){
        my $file = basename($filename);
        print STDERR "($i) $sub ${file}::${package} line $line\n";
    }
    print STDERR "\n-------End Stack Trace-------------\n";
}
