I'm creating a parallel link checker in mod_perl using LWP::Parallel::UserAgent. Are there going to be any problems by instantiating the PUA as a class variable? I only see the object being created when apache starts - not when new child proccess are created or when there is a reload - does this mean that all the process's will share the same PUA? As I've run this on several larger sites - I've noticed my memory us has sometimes pegged up to 11M, and then never gets smaller. Any ideas? For example: use strict; use vars qw($VERSION $PUA); use LWP::Parallel::UserAgent qw(:CALLBACK); use HTTP::Request; use HTTP::Response; unless( ref $PUA ) { $PUA = LWP::Parallel::UserAgent->new(); warn("$$ created new PUA"); } sub handler ($$) { $PUA->initialize(); ... # Create a closure to store $self my $callback_parse = sub { $self->callback_parse(@_) }; foreach (@requests) { $PUA->register($request, $callback_parse ); } $self->body($r); return OK; } sub body { my($self, $r) = @_; $PUA->wait(); ... }A
