APAR Error Description / Circumvention

-----------------------------------------------
A case exists where the iSCSI TargetNode Connection object is
destructed when its destruct timer executes, which causes a
system exception be thrown, leaves the Connection objects
around, and results the NWSD vary on failure.  This mostly
happens when HWT is used and  GEO-mirror is configured.

The problem is made evident by the following two LIC Logs being
generated: 5000 6512 and 5000 6520.

CORRECTION FOR APAR MA43368 :
-----------------------------
Code has been added to prevent the connection object be
destructed while the timer executes.

CIRCUMVENTION FOR APAR MA43368 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions
