This one might be a bug, but we need the full stack trace and possibly data + request to reproduce. If this can be reproduce with 2.1.2 please attach the information to a bug report at jira.codehaus.org > However, if you do exactly the same but with a vector data set (in EPSG:4326) > and published as WMS, then it works! Completely different code path, the "direct raster path" is enabled only if there is a single raster and it's significantly faster (and scales up a lot better), when there is more than one layer that code path cannot be used and we fall back on the slower, but tested over more years, generic map building path. You can disable the direct raster path by giving the JVM running GeoServer the following system variable: -Dorg.geoserver.render.raster.direct.disable=true With that one enabled you'll use the old and more tested (but slower) map rendering code for single rasters as well.
