Hsie,

That was me.  I was caught off guard by the NWS announcement yesterday
that the GOES-WEST GINI images in NOAAPORT were being compressed
starting today (and the GOES-East will be compressed starting
tomorrow).  I had been working under the assumption that this change
was going to occur in late August/early September.  I learned of the
change yesterday at about 2 pm.

I spent the rest of the afternoon cutting a new ldm-mcidas distribution
that has a new utility, zlibg2gini, that will uncompress the Zlib
compressed NOAAPORT images.  I then installed this release,
ldm-mcidas-2003, on all of the machines receiving the IDD NIMAGE
datastream that I have access to with the intention of informing folks
about the change this afternoon.  rainbow and blizzard are two of these
machines.  I apologize if doing the installation was unwelcome.

This is very strange.  The same binaries are running on motherlode.ucar.edu,
also a Solaris Sparc 5.8 system, with no errors.  I am investigating the
problem on blizzard now.
