hi,

we had similar problem with our implementation (though we used C=20
binding). i was not the one who worked with it directly, but AFAIR it=20
was some non-obvious trick related to enabling a sort of a keep-alive=20
mechanism in libprelude, to prevent connection closing every few seconds.=


you can take a look at our C++ implementation of libprelude data=20
handling in ACARM-ng system (http://www.acarm.wcss.wroc.pl). the part=20
you're interested in is Input::Prelude namespace, namely:
http://repo.acarm.wcss.wroc.pl/main/src/inputprelude/Input/Prelude/

hope that will help!
