If you can I would post some code. I have not found in my personal experience anything like you are talking about between 5.6 and $VERSION >= 5.6. I work on a few gig of mail data a day, and I dont see any leaks. It could be that you aren't localizing variables, or possibly using local versus my, and the variables are never going out of scope.

Just some thoughts, but again if you can, post code so we can test. If you can't post the original content, post some code that reproduces the leak.

MMMMM... Chocolaty Perl Goodness.....
