SOE Reports Some Spawn Times Slower Than Intended

In a SOE forum thread about the slow spawn times of living steel, molten steel, living blades, empowered blades, a steel cyclone and a steel hurricane in Argath, Absor, EQ Developer stated the following:

Actually, those NPCs spawn very, very fast.  Unfortunately, there is some sort of issue with the large number of people in those zones that we've not seen before causing them to spawn super slowly.  We're looking at a way to fix it soon.

It is unclear if the "zones" he is referring to means that there are problems with spawn timers in other zones as well.
