FIX: Session Integrator may not decrypt data in Host Integration Server

Symptoms

When you run a Session Integrator session in a Microsoft Host Integration Server 2013 or Microsoft Host Integration Server 2010 environment, the session closes intermittently.

Additionally, a Session Integrator server internal trace that is captured by the Host Integration Server SNA Trace Utility may show a trace output that resembles the following:

DecryptMessage produced too much data, room = 761.

Decryption Failed.

Cause

This issue occurs because of a mismatch between the decrypted data size and the receive buffer.
