WCS: error on creating large Geotiff from ECW

[Bart van den Eijnden]

Hi list,

I am trying to create a Geotiff file from an ECW file using Mapserver WCS
(Mapserver 4.8beta2, GDAL CVS 04/01/06, ECW SDK 3.3RC1).

The request is:
http://[ip]:[port]/cgi-bin/mapserv480?map=/data/OGC_UMN_services/basispakket_dkln.map&bbox=157200,456945,161080,459273&service=WCS&version=1.0.0&exceptions=application/vnd.ogc.se_xml&request=GetCoverage&coverage=AAA154&crs=epsg:28992&resx=.5&resy=.5&format=Geotiff

The following error message occurs:

error: could not get data:
NCScbmReadViewLineBIL failed.: Unable to access file. GDALRasterIO()
failed: drawGDAL()

The same part of the ECW can be rendered by Mapserver WMS without
problems. When I try a smaller WCS request, it does work.

Any ideas what could be the problem and how to solve it?

Thanks in advance.

Best regards,
Bart
