wms raster rquest crash!

Well that's some new information!  You didn't mention that this image
was working in MapServer before you had trouble.

Are you certainly that you rebuilt MapServer with a current and complete
set of supporting libraries, particularly the current versions of
libtiff and libgeotiff?

Hi Frank and Ed, thank you for your responses.
We are currently using GDAL 1.1.9.0, released 2003/06/27.

Up till I posted this problem, our Admin has helped us try all the
latest gdal versions in no vail. We do have successfully set up the the
same wms on the same box and another box before. But since we recompiled
everying of mapserver from the latest releases, we encountered the
current problem. And now even we tried switching back to some earlier
releases, it was still not working(well, it really should).

Not sure whether or not data could be causing this the problem because
we used the same data before. Here is the file anyways.

Sincerely,

Haiyan
