Customer Environment
==================
eLink TCP3.1 running  at RP# 19
Sun Solaris 8. (4 cpu Ultra - 4 )

==============
Customer Problem
===============
The CICIS Handler has a Multiplex of 7 and the gwiconfig has a Maxconnect of 2.

At bootup the connection messages seem to verify the correct multiplex of 7 and maxconnect of 2.
=> GWIDOMAIN.PID: LIBGWI_CAT:1057: INFO: Multiplex count for connection 0 is 7
=>GWIDOMAIN.PID: LIBGWI_CAT:1057: INFO: Multiplex count for connection 1 is 7

Intermittent CICS problems result in service timeouts and the service timeout messages show
the MULTIPLEX number being higher
Example:
=> GWIDOMAIN.PID: LIBGWI_CAT:1115: WARN: Deleting timed out session 1/13

What appears to be happening is the contents of the right data field,which is supposed to show the session-nbr,
contains invalid information.

Below is a set of ULOG messages corresponding to the GWIDOMAIN that is associated with the customer Foreign connection
to CICS mp03.
