IBM 3174 Support C - Rel. 5.0 Causes Negative Bind Response

SYMPTOMS

In the event that the Customer Information Control System (CICS) region goes down, CICS will attempt to renegotiate the LU 6.2 SNASVCMG mode sessions as the first step in getting the connection back to an active state. It does this by sending down bind requests to SNA Server. When talking through a 3174 Establishment Controller running Configuration Support C - Release 5.0, SNA Server may reject these bind requests which will cause the sessions, and therefor the connection, to stay in a pending state.
