          Bug - A problem that impairs or prevents the functions of the product. MODCLUSTER-391 mod_cluster and mod_proxy integration

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
