APAR Error Description / Circumvention

-----------------------------------------------
Network File System version 4 (NFSv4) name registry daemon job
(QNFSRGYD) may encounter MSGMCH3601 (Pointer not set for
location referenced.) T/QZNFRGYPC when accessing an NFSv4
mounted file system.

CORRECTION FOR APAR SE61229 :
-----------------------------
A timing window exists where a name request might be abandoned
by the client while the NFSv4 registry daemon is processing the
request.  This PTF adds tighter synchronization to the registry
request processing to prevent the request data buffers from
being freed while the request is being serviced.

CIRCUMVENTION FOR APAR SE61229 :
--------------------------------
None.
