Yes, but the problems encountered then are usually of the "I can't connect
/ post binary attachments, what's wrong?" variety.

Well, FreeBSD with 200 GB; ~news/db/history is 1.6 GB, from last night's
news.daily run:

On a machine with a bit less memory and about half the spool but with INN
2.2 (instead of 2.3), expire takes almost three hours to run.
