PI24001: THE JSPWRITERIMPL IS NOT PROPERLY CLEANING UP RESOURCES IN MEMORY AFTER A REQUEST COMPLETES.

Fixes are available

APAR status

Closed as program error.

Error description

The PageContext pool is designed to accept a limited number of
objects.  When requests complete, the PageContext instance is
returned to the pool for reuse by another request.

If another PageContext is released to be reused again and the
pool is full, there is a chance the JspWriter resources are not
cleaned up properly.

****************************************************************
During high load the JSP container can generate several
PageContextImpl objects which might not be reused. These
PageContextImpl objects reference an array of BodyContentImpl
and a JspWriterImpl object.
Discarding the PageContextImpl objects, without correctly
recycling the BodyContentImpl objects and the JspWriterImpl
object, causes a memory leak.

Problem conclusion

The JSP container was modified to dereference the objects
causing the memory leak facilitating the garbage collection of
them.

The fix for this APAR is currently targeted for inclusion in
fix packS 7.0.0.37, 8.0.0.11, and 8.5.5.5.  Please refer to
