Hi, Thomas --
Thanks for providing so much helpful information. At the moment,
everything you've done looks right. The "ran out of input while
spooling..." message means that the size of the subset that got
written out did not match the requested grid. To find out what
happened, you have to put your server in debug mode <log level=debug>
and then make the request. You'll see in the log file a long command
(with "nice" in front of it) that invokes GrADS, runs the subset.gs
script and outputs to a file under the $GDSHOME/temp directory. If
you could please run this command manually, outside the GDS, and send
along the complete text of the GrADS session as well as the size of
the output file it created. Please do the same with the request that
works too.
