APAR Error Description / Circumvention

-----------------------------------------------
A save operation may fail with MSGMCH5204  and VL07000120,
VL04030030, VL02000307.  In other cases the save operation may
hang.  Other VLOGS issued may include VL07000107, VL07000105,
VL2E000200, VL10001080, VL10007011, VL10007002 and VL07000101.
Other messages issued may include MSGMCH5203 and MSGMCH1668.
Subsequent save operations may result in MSGCPF3795 RCC4E6 if
the initial save operation which failed was using save while
active.  If this occurs an IPL is necessary in order to clear
the condition causing the RCC4E6.

CORRECTION FOR APAR MA39266 :
-----------------------------
Two LIC tasks were accessing the same internal storage area
(segment) concurrently.  If one of the tasks required additional
storage to be allocated for this segment  the other task could
start using that storage before the system was completely done
creating it.  This led to a situation where the first task would
sometimes clear the storage after the second task had already
started using  it. The system code has been changed to prevent
the task from prematurely accessing the storage.

CIRCUMVENTION FOR APAR MA39266 :
