This doesn't seem to have created a "fetchnews.log" file as I
expected, so below's a copy & paste from the terminal window. It's
227 lines, so I figure that's within 15% of "fine for the list":
# valgrind --leak-check=yes --show-reachable=yes --num-callers=16 --

# updatedb
# locate fetchnews.log

I've been getting the "Warning: skipping group "alt.", invalid name
(NULL component)" and "ERROR: FETCHNEWS MUST REFETCH THE WHOLE ACTIVE
FILE NEXT RUN." messages for some time, both on this machine & it's
predecessor and I always figured it was something to do with my ISP's
server. Is this anything to worry about? I repeated the run using
three or four servers I found listed at <http://freenews.maxbaud.net/
> and excluding to Eclispe server and didn't see this message, so
that tends to support this theory. These messages have never bothered
me because I am happy to be able to read & post news. The second run
is at <http://linux.stroller.uk.eu.org/fetchnews2.txt.gz>
Thanks for all advices,
Stroller.
