APAR Error Description / Circumvention

-----------------------------------------------
A partition terminates with a B6000103, with no apparent cause.

CORRECTION FOR APAR MA48144 :
-----------------------------
On Power7 servers and earlier, towers can be connected to the
CEC via RIO loops.  When Collection Services is running, it
accesses performance information for the RIO loops.  Low level
synchronization objects called spinlocks are used in this path,
which is not allowed when the task is pageable (able to
encounter page faults on its stack.)  The task is now switched
to a non-pagable stack before running this code.

Even though this APAR is hiper, customers should not interrupt
normal business operations to apply the PTFs if their servers do
not have RIO loops (RIO-G or RIO-IB).  Although the problem is
very rare, customers with RIO loops may wish to disable
Collection Services until the PTFs can be applied.

CIRCUMVENTION FOR APAR MA48144 :
--------------------------------
Disable Collection Services using the command ENDPFRCOL
FRCCOLEND(*YES).
