Well, I had a full feed before but expired articles after 1 day. Now it's
set to 2 days.  Before I ran expire ever 2 hours to make sure 9Gb disk
doesn't overfill(it stayed at about 5Gb on average).  Now when it starts
it never finishes. I am actually thinking about zapping the /var/news
spool and starting it all over, and keep them for 1 day at first. And then
gradually increase.

This helps. Here is another question then.  At first the process seems to
run fine and creates a 60meg history file, but then slows down and I never
say it go beyond 70 meg yet.  The original history file is about 200meg.
would this mean that it runs out of some resource and waits for i/o? I
guess I would need more memory since cpu stays free for 70% of the time,
and there is plenty of hdd space left.

This is also a possibility, but i am stuck with them :(

Well, I hope when I get it all worked out it will be 4x9GB since the goal
is to keep the articles for 5 days.

Thanks.
