I'm on.

The current LDM logfile contains the following:

    Jun 30 20:01:58 glacier pqact[523476]:   318271 20040630200158.002  NIMAGE

 write error

This indicates that the pqact(1) process 523476 was unable to pipe the
data-product whose product-identifier is

    satz/ch1/GOES-12/IR/20040630 1955/PR-NATIONAL/8km/ TIGQ02 KNES 301955

to the decoder whose pathname is

    /home/disk/ldm/local/bin/gini/zlib2gif.pl

because the pipe was closed.  The pipe could have been closed because

    1.  The decoder explicitly closed standard input; or

    2.  The decoder terminated prematurely.

There are other, similar entries in the logfile.

Offhand, I'd say the decoder

    /home/disk/ldm/local/bin/gini/zlib2gif.pl

has a problem.  Does it log error-messages anywhere?
