Hi Scott,
We have run into similar issues when sending big messages outbound with a client connection. For any messages that were too large, we needed to set up an MQ server connection and define the message length in the MQ definitions. We could never get Cloverleaf to work with client connections and messages over 4 meg. It sounds like you are reading inbound and have already examined the MQ setup. Unfortunately, I don’t have a solution for you but wanted to let you know we have experienced similar problems.
Good luck,
Amy Gray
