Hi Bryan, glad you figured it out. For the record, GWC's 900913 gridset used to come with 31 zoom levels. That means up to 0.0001m pixel resolution, which also means a full coverage of 1000 billions x 1000 billions tiles at the higher zoom level. Which, if my math is correct, means a fully seeded layer with a rather small average tile size of 4KB would take more than 3.7 billion terabytes. Besides I don't think there's a single GIS dataset with a spatial resolution of 1x10-4m. The WMTS spec defines it up to zoom level 18. That proved to be too low for some users, so on trunk we restored back the gridset definition to its original shape. But I still think it wouldn't make sense for zoom level > 24 (i.e. almost 1mm spatial resolution), which is still 33.5M x 33.5M tiles at full world coverage. Which still would be 4 billion terabytes for the highest zoom level with 4KB tiles. Hopefully you define your layers with a restricted number of zoom levels. But it'd make sense to have something saner as a default value, hence the idea on limiting the number for pre-defined zoom levels, although you can extend them if you want.
