I have set up an image pyramid based on 5 levels of tiling. The data is served using the ImagePyramid plugin for GeoServer. When I do a layer preview the data is visualized just like I expect them to be. But when I zoom in a couple of levels, I get a white tile in return.

The GeoServer log tells me the following:

If I zoom in a couple of levels further, I get data again.

The extent of the data is [530000, 6220000, 540000, 6230000] and the projection EPSG:25832, which the GeoServer admin interface agree on.

Then what could be the reason for GeoServer to look inside the BBOX [-1, 0, -1, 0], when my data is inside the requested map?
