Local fix Problem summary
****************************************************************
* USERS AFFECTED: Dynamic Cache users that have servlet        *
*                 caching enabled and applications that        *
*                 return large servlet responses.              *
****************************************************************
* PROBLEM DESCRIPTION: Memory Leak in FragmentComposer for     *
*                      applications with large servlet         *
*                      responses.  The servlet response is     *
*                      written to the cache buffer even in     *
*                      the case where the fragment is          *
*                      non-cacheable.                          *

* RECOMMENDATION:                                              *
****************************************************************
There is a memory Leak in FragmentComposer for applications
with large servlet responses.
Problem conclusion
Disabled writing to the caching buffer for servlet responses
that are not cacheable and have no parent fragments that have
consume-subfragments set to true.
