I've an XMS program (my first one), and it works fine with small messages, however when I have a big message (ie > 4 MB) it reads the message but the connection with the server remains open (after connection.Close()) and when I terminate the program the read message reappaeras on the queue ?

The Java program that is putting the message works fine (as well as a Java test program to read the message).

Any tips, or is this a bug ? The server is an iSeries MQ 6, the client software MQ 7.1

How good is your program's error trapping? 4Mb is the default limit for a lot of WMQ objects & you could be getting a "message too large" error that you're not responding to.

Is the Java program making the same class of connection as your application?

Uhm, sounds like there's a failure to commit.

Just ignore the question... I installed 7.0.1.3 and everything works fine now (using the normal .NET code as well which had the same issue).
