APAR Error Description / Circumvention

-----------------------------------------------
When multiple users are viewing the same MSD and both request
the same HvData, the HvData data address can be corrupted. The
corruption can cause unpredictable results when displaying MSD
data.

CORRECTION FOR APAR MA45673 :
-----------------------------
The LIC MSDMgr was changed by adding a gate for serialization of
the access to the HvData.
This prevents the data address corruption.

CIRCUMVENTION FOR APAR MA45673 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


None.

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
