Same port worked for just 3 servers before rehanging. New port worked like a fresh instance.

Yes. That mirrors the behaviour I'm seeing. If you retry the original port some time later--I haven't tied down how much later yet--it "recovers", which suggests this is a timeout issue, but I am at a loss to see where else to apply timeouts?

I;ve no reports of the same behaviour under *nix (yet), so this may be a windows-only problem. I guess I'll have to write the equivalent code in C to isolate whether it is windows itself, or Perl on windows. Which is a pain in the butt.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
