When tracing messages using the "trace" property to the destination and having +MSG in the log_trace or console trace, we see the message ID is printed in the format of "ID:EMS-SERVER.20448D0050B3:1".

This is like “ ID:&ltEMS server name>.&ltnumber 1 >:&ltnumber 2>”. The  EMS server name is the name of the server defined in the tibemsd.conf file and “number 2”  gets incremented for every successive  message sent from a session on a given connection.

“number 2” gets incremented whenever "send" is called irrespective of which session sends a message on a given  connection.  “Number 1> will be different for different sessions.  This will provide an idea of whether the session is sending or different sessions are sending messages on a given connection.
