Hi,
I've compiled MapServer with Gdal and Ecw support in Linux and it I've got an 
error when I request an image in a small scale in this conditions:

Image Size: 350830x661256 px, 17530964 KB
Bounding Box: 
724484.334581317,4346590.549035932,725775.6088994413,4347793.168699379
Request size image: WIDTH=335 HEIGHT=312
Exception:
Error 48 "Could not perform Read/Write onGDALRasterIO() failed: drawGDAL(): 
Unable to access file. GDAL
RasterIO() failed: drawGDAL()

If I request a bigger image I can obtain this error with a smaller bounding 
box. In windows with the same image and request parameters and the same 
server conditions I don't get any error. I thought that the problem is in 
Gdal but I am not sure.

Best regards,
