Considering the HTT security announcement, I'm not sure HTT should be
enabled on any production boxes. That being said, you may want to
investigate the usability of ULE in your situation, assuming it
shipped with 5.4 (Which I'm not sure of). In some specific instances,
I've seen switching to ULE solve problems of this nature, although it
may simply bring up whole new ones.
