=========================================                                       
System abort 1458 or System abort 2559 (CM Suddendeath 311) if a                
network connection is lost during the NEWCI command.                            
                                                                                
The issue is that a jsmain process may clean up all of the session's            
resources before all of its children have died.  We believe that the            
fix to this may also fix other system aborts relating to adoption which         
have very similar symptoms.

The failing process will have failed to touch one of the session's              
data structures because it has been released.  The jsmain associated            
with the session will have cleaned up the session and put the LOGOFF            
message onto the console.  The trace of the NEWCI failing the system            
looks something like this:
