Abstract

LIC-OTHER-SRCB6005121-INCORROUT CONCURRENT ASP BALANCES CAN
LEAD TO EARLY STRUCTURE REFERENCE

Error Description

When two or more ASP balance activities (against different      
ASPs) are started at very nearly the same time, for the first  
time since an IPL, a common data structure is referenced by    
second balance, while still being set up by the first.

Problem Conclusion

The problem is fixed by allowing only one balance look for the  
existence of the structure at a time.
