Is this happening when using GetFeatureInfo only? The request
GetFeatureInfo makes against
a raster data set is pretty small, 5x5 pixels, maybe the JDBC mosaic plugin
is not good at extracting
only the part actually requested from the overall dataset. Or maybe level 0
has giant tiles?
Not sure, have little/no experience with the JDBC raster pyramid plugin.
