+++ This bug was initially created as a clone of Bug #171756 +++ Memory leak in the worker MPM (worker.c) for Apache 2, in certain circumstances, allows remote attackers to cause a denial of service (memory consumption) via aborted connections, which prevents the memory for the transaction pool from being reused for other connections.
This issue should also affect FC3
From User-Agent: XML-RPC httpd-2.0.54-10.3 has been pushed for FC4, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
