APAR Error Description / Circumvention

-----------------------------------------------
A extremely small timing window (micro-seconds) exists where the
delete of iSCSI TargetNode Connection object happens at the same
time its destruct timer executes, thus calling the same function
at the same exact time (within micro-seconds of each other).
Therefore the two functions compete over releasing
links/resources and cause each other to halt processing, which
leaves the Connection objects around.

The problem is made evident by the following two LIC Logs being
generated at the same time:
5000 6512
1F00 0016

CORRECTION FOR APAR MA42085 :
-----------------------------
Code has been added to serialize this, so that only one can
process the release at a time.

CIRCUMVENTION FOR APAR MA42085 :
--------------------------------
None.


Activation Instructions
