If you never read more than one file at a time, I'd suspect a memory
leak. The HDF-EOS functions contain lots of pairs of book-end
functions: if you open something, you should close it. If you attach
something, you should make sure to detach it, etc.. In general, the
first one of each pair allocates resources (usually including memory),
and the second function must be called to deallocate them; if it isn't,
you have a resource leak. Check all of your calls to such functions,
and make sure that they're matched up properly.
