APAR Error Description / Circumvention

-----------------------------------------------
MSD showed LIC Logs had been created for exceptions in
SkCacheHighUse in both SkCache::getMsg and SkCache::free
methods. These LIC Logs showed an SkCache had been corrupted
which caused errors when communications buffers were allocated
or freed on some processors of the system.

CORRECTION FOR APAR MA47473 :
-----------------------------
The SkCache objects had been allocated from the same storage
used for the communications buffers themselves. This fix moves
the SkCache objects to a separate storage heap to lessen the
chance that they will be corrupted.

CIRCUMVENTION FOR APAR MA47473 :
--------------------------------
None.
