I think there might be a relation between these errors and the memory use.
What makes you think that? It turns out that both modules export a constant named SUCCESS, and that is the source of the warnings. But it has nothing to do with the memory leak. The OP is using the fully qualified name $File::DirWalk::SUCCESS, so there's no need to import anything from that module, and "use File::Dirwalk ();" should squelch the warnings.

That said, I agree with some of the reviewers of File::DirWalk in that I don't see any advantage of this module over File::Find.
