When you say "failing" do you mean a hard fail or that they fail when  
things are unserialized? With my PHP client/worker code I was running  
into UTF8 problems when using strlen() (which isn't unicode aware). If  
your results can be in UTF8 and the Perl code isn't accounting for  
that then things could be blowing up for that reason. Again, this was  
a PHP-only problem I ran into ...
