I've fixed it, at least in terms of the shared scalar : )

If I declare the scalar with "our", and then update it in the processMessage sub using "$FeedAgent::sharedTestVar++;" then it works.

not sure why this works, but it does !!

Once again thanks very much for your help guys, I'm going to need to share the deeper levels of the shared hash of hashes as you mentioned before
