APAR Error Description / Circumvention

-----------------------------------------------
It has been discovered that a STRCAD could encounter a hang
condition if QFPATMAP had been damaged due to being updated
while at the same time as being read.
This is a rare circumstance and code is being enhanced to avoid
such a situation in the future.

Work Around: With Cluster Active on all nodes in the cluster and
all related jobs, admin domain can be in an Inactive status. The
node where the damaged index resides can be removed from the
admin domain, then admin domain can be started to ensure all
other nodes get updated and show consistent MREs. The problem
node can then be added back into the admin domain.

CORRECTION FOR APAR MA46923 :
-----------------------------
Code will be changed to prevent the read from happening at the
same time as an update.

CIRCUMVENTION FOR APAR MA46923 :
--------------------------------
None.
