I just verified that the same thing is happening on two different kinds
of systems maintained by the UPC: Sun Solaris SPARC 5.9 and Fedora Core
Linux 1.

The cause of the problem is unknown to me at this time.  I will need to
dig into pnga2area as soon as I am able.  This may not be for a few
days, however, since I am currently in Sao Paulo, Brazil, and getting
the time to review code and come up with a fix will be hard to find until
I return to Boulder.  The really strange thing about the big files is
that they seem to be OK, or at least I can list out information from
them with no problems!?

Thanks for bringing this problem to my attention!  I will attempt to
get to the problem as soon as I am able.

Cheers,

Tom
