Here is how I did it. I stopped going to new dungeons. I went to my previous dungeons and cleaned out all the loot I'd left (don't know if that had any effect specifically). Instead, I spent my time in the outdoors collecting ingredients, hunting, fishing, and mining then going back into town (I'd only really been to the first two yet) to perform alchemy, enchanting, and blacksmithing.
The 200 kbs appear to have cropped up when I accidentally ran into a clear-able area and then when I decided to visit the college to see if they had another alchemy merchant. I explored the college extensively including going into a few places that may have counted as a dungeon where cached data is concerned.
Now, the problem still needs to be fixed, but this is at least a way to spend the time before the patch. That being said, from the sounds of it, most of you are over the limit.
