The underlying SRTM elevation data is known to have many voids in the Himalayan area and a reasonable explanation _might_ be that the void filling in TerraGear doesn't provide too realistic results. For your own experience, you'll find a copy of the respective elevation raster here as a geo-referenced 1x1 degree TIFF image: ftp://ftp.ihg.uni-duisburg.de/GIS/GISData/SRTM/version2/GeoTIFF/Eurasia/N28E083.tif Note that these images have a 16-bit grayscale channel, therefore simple "visual debugging" on a typical PC screen might be quite tricky due to limited colour depth. In order to get a better clue about the reported errors I'd consider it as being highly desirable looking at a similar error at a place which is located at a much lower elevation.
