Request context mismatched error (Poller) about cpppo HOT 2 OPEN

At a brief glance, it appears the the Ethernet/IP CIP connection stream is getting a mis-matched response to an issued request; almost as if it issues a request, times out on a response, and then issues another request and receives an non-matching response.

I would need to see the entire Python application to ensure that you are (properly) discarding the proxy session on all errors (ie. never catch exceptions and ignore them within the lifespan of the proxy. If a request fails (ie. times out) -- you must discard the session and establish a new one!

It reads out 12 tags which are the digital inputs, and nothing more...
