Ruzi the connection handle in a CICS app isn't a 'normal' connection handle - it is actually the CICS region itself is connected to the qmgr, CICS just lets the application use one of these handles. The contents of the handle are 0 - before and after - and that is normal.
I really think this is a problem with the MQXCNVC support (like maybe it isn't supported from C/CICS) rather than it being an application problem.
