Yes , always in that area it gives me the same error. But if I use a BBOX
with a smaller range keeping the same tilesize (256x256) it works fine (
not always)
I am running WMS requests to generate a 256x256 tiles at different zoom
levels.

OK , I set up this option in the map file but where have I to check the
error ?
Thanks for your quickly response.
