Sorgath and the Terrible, horrible, no good, very bad server lag.

Apparently there is some sort of issue with the sorgath temple under the prairie.  When someone is in the temple, the server lags horribly.

Example, last night, was just me and Talvi on.  Server was running relatively OK.  Talvi went off into the temple, and I was just walking around restocking, sorting inventory, ect.  As soon as Talvi got into the temple, I was getting MASSIVE lag spikes; lots of 'rubberbanding/boomeranging' while trying to walk across areas, NPCs/doors/usable placeables not rendering on screen for upwards of 30 seconds after I arrived at their location, my inventory screen taking likewise 30 to 60 seconds to actually display what I had equipped or what was on a given inventory tab, converstations with NPCs taking forever.  Pretty much pure suck.

As soon as Talvi left the temple.... the lag spikes stopped immediately.

This behavior has been consistent and repeatable for a couple months now.  Someone enters the temple to hunt serpent disciples, the entire server lags like crazy, to the point of near unplayability for everyone outside the temple.  It also seems to be linked to the TMI errors that pop up every time someone enters macedone.  The temple generates TMI errors as well (slaves perhaps? Not sure what would cause the lag on the second level of the temple though as there's no slaves down there).
