Closed as program error.
| Error description
APACHE/IHS calls our initialization routine twice. Because our
plugin
can only stand to be called once there is a check that is
performed so
that it is only initialized one time. However sometimes a race
condition can be encountered which results in the plugin not
initializing at all. Local fixProblem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server users of *
* IHS on UNIX Platforms. *
****************************************************************
* PROBLEM DESCRIPTION: Intermittently IHS fails to load the *
* IHS plugin. No trace plugin trace *
* file will be produced and user will *
* see that ALL requests that should *
* be handled by WebSphere will return *
* with 404. This is a problem that *
* the user will see immediately after *
* starting the IHS webserver. *
****************************************************************
* RECOMMENDATION: *
****************************************************************
At times when certain race condtions occur the WebSphere
plugin for IHS/APACHE will not initialize. No errors will be
produce in the IHS/APACHE error_log but because the plugin
initialization fails, no plugin trace file are produced. When
this problem occurs users will notice that ALL requests that
should be handled by WebSphere will return with 404.
This is an intermittent problem which only would occur on UNIX
platforms. Problem conclusion
Modified the IHS plugin to avoid the race condition that caused
the plugin to not initialize. Temporary fix
