-156 RQMRG ERR OUT OF SEQ MSG (Magic xpa 2.x)
The session between the client and the server is no longer synchronized.
A context serving a client received an event from the client containing an unexpected session counter. (Each request from a client must have a session counter equal to the previous session counter + 1).
If possible, reproduce the problem by setting the Log parameter to Enabled in the Mgreq.ini file (log = Requester.log Y R) in the directories of the requester and the enterprise server.
