LU2 API problem

**************> QUESTION level 1 --> level 2 SPECIALIST <**************         
                                                                                
Question:                                                                       
one of my customer has an LU2 application that runs fine                        
using SNA Server 2.1 (level 1.3.93.495 + U427073/4) after                       
upgrading to 2.1.2 (level 1.3.95.050 - U436836/7) the                           
application fails: it stops on a snaread waiting for                            
the first screen sent from host.                                                
The snatrace doesn't show any error and till SSCP-LU                            
sessions activation behaviour and snatrace contents                             
are the same.                                                                   
Customer has had to go back to 2.1. We know there are newer                     
levels of SNA Server for AIX 3.2 nowadays but we must be sure                   
this problem has been fixed before going further.                               
A known problem?                                                               
Thank you very much for your support, best regards, Marina.

There was no change in the interface for SNAREAD between                        
the two levels so this does look like a defect.  I would suggest that           
you bring your 2.1.2 SNA server code up to the latest PTF level -               
U441784/5.  I do not know of a specific fix for this problem but your           
level is old and there have been many fixes out since those.                    
If that does not resolve the problem, you should report your problem            
as a defect through your normal channels.
