PQ57837: IHS WAS PLUG IN SEGFAULTS AT EVERY REQUEST.

APAR status
Closed as program error.

Error description
There appears to be a problem with how the plugin performs
initialization on Unix platforms.  There is a slight chance that
the WebSphere initialization can be skipped sometimes.  When
this happens the server will core dump repeatedly.
Local fix Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server version 4.0.0,  *
*                 4.0.1, and 4.0.2 user of the IHS/Apache      *
*                 plugins.                                     *
****************************************************************
* PROBLEM DESCRIPTION: All requests made to the webserver      *
*                      result in a core dump.                  *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The plugin had a check to avoid initializing twice on Unix
platforms(An IHS/Apache feature).  This check expected the
parent to be gone on the second initializer call.  It is
possible for the parent to still be around on the second call
and as a result the plugin would never initialize.  Therefore,
all requests would core dump.
Problem conclusion
There is nothing wrong with having the plugin initialize twice
since all data from the first initialization gets destroyed.
So the check was removed and now the plugin initializer runs
twice.
