JMS, MQ WebSphere and message loss

Hi all

I have a rather strange periodic problem.

I'm sending messages from ERP to XI to MQ Websphere. Sometimes messages does not reach MQ. There is a twist on my scenario. When XI receive a message from ERP XI creates 3 messages: Begin, Data and End. This is becaus the receiving application needs these. It is always my Begin message that gets lost.

The three messages are created using an graphical mapping program and an enhanced interface determination.

The problem happens once end a while - about every 1000 messages or so.

The JMS adapter is configured with Transport/Network protocol: "TCP/IP" and JMS compliant: "webspehere (non JMS)". I'm also using "transactional JMS session" and content conversion.

All messages in runtime workbench is status succesfull (delivered).

Any suggestions?

Kind regards

Martin
