SYMPTOMS
========

SNA applications using the LUA SLI (Session Level Interface) API may randomly
fail, and require that SNA Server be stopped and restarted before the
application can recover.

When the problem occurs, an SLI_SEND verb will fail with a primary return of
LUA_PARAMETER_CHECK, and a secondary return code of LUA_DATA_SEG_LENGTH_ERROR,
even though the data length is correct.

CAUSE
=====

A problem in the SNA Server SLI library when calculating the extent of an array
caused a validity check for the data segment length parameter of an SLI_SEND
verb to return false.

RESOLUTION
==========

SNA Server 3.0
--------------

3.0. For additional information, please see the following article in the
