APAR Error Description / Circumvention

-----------------------------------------------
The SMVLOG-RECORDER task has ended and the system is not able to
store smVlogs.

SmVlogs are normally used during the early part of the system
IPL before full paging is reached. Then the permanent LIC Log
interface is started. SmVlogs can be used at anytime after the
IPL, but there is only a few LIC programs that use it. So the
exposure of missing any smVlogs is during the IPL and for a few
LIC programs. The task ending is triggered when a LIC program
takes an exception in the middle of generating a smVlog.

CORRECTION FOR APAR MA42107 :
-----------------------------
When the exception occurs, Exception management calls the
destructor of the smVlog object. The LIC program wasn't able to
store the smVlog because of the program exception interrupted
the program before the EndEntry method could be called and
executed. This causes the SMVLOG-RECORDER task to take an
exception when it tries to stores the smVlog.

The LIC was changed to handle the EndEntry and the destructor
being out of order. The LIC SMVLOG-RECORDER task was changed to
tolerate an exception and allow it to continue running.

CIRCUMVENTION FOR APAR MA42107 :
--------------------------------
None.
