APAR Error Description / Circumvention

-----------------------------------------------
Customer has a R720 partition that hangs and does not recover.

The problem appears to be unrelated to workload.
There is no way to access the partition even via the console.
HMC shows the partition is ACTIVE with no SRC posted.

CORRECTION FOR APAR MA45355 :
-----------------------------
Instead of having the static paging task adjust the number of
static paging tasks, we will create a stand alone task to do
this work.  If the new task encounters a page fault, the static
paging tasks will complete the IO as normal, and the system will
not hang.

CIRCUMVENTION FOR APAR MA45355 :
--------------------------------
None.
