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?
