Ok, as you have seen in my first e-mail, I have installed Perl 5.8.0 RC2. Now, I'm moving to RC3 and and tomorrow I will tell you what happens. Thanks for the moment,

You should be able to use Thread::Pool for this. $pool = Thread::Pool->new( { workers => 10, # or higher or lower, max simultaneous requests do => sub {fetch from URL and return it}, } ); @jobid = (); push( @jobid,$pool->job( $_ ) ) foreach @url; foreach (@jobid) { my $result = $pool->result; # do whatever you want with result X } >your problem is that you use the *old* threads (5005threads, pre-5.6.0), >whereas mod_perl 2.0 is using ithreads (5.6.0+). >>>my $t2 = new Thread(\&my_thread,'t2'); >do 'perldoc threads' with perl-5.8.0 Actually, to add to the confusion: only the Thread.pm and Thread::Signal.pm modules are old 5.005threads modules. All the other Thread:: namespace modules (except Malcolm Beattie's old version of Thread::Pool on CPAN) are new "ithreads" modules. Only the true "pragma" modules threads.pm and threads::shared.pm have remaind untouched. This was changed last week, as described in Rafael's p5p summary http://use.perl.org/article.pl?sid=02/07/15/0732235 ;-) Liz
