Hmm, my db dir looks like this:

total 305487
-rw-rw-r--    1 news     news       252787 Sep 22 03:06 active
-rw-rw-r--    1 news     news       252734 Jul 24 10:13 active.old
-rw-r--r--    1 news     news           84 Jul 24 10:13 active.times
-rw-rw-r--    1 news     news     248833806 Sep 22 17:36 history

Old articles are automagically expired out of history by the expire.ctl
setting when news.daily runs, right?  My expire.ctl says: /remember/:7.

I don't know how to check on a memory-mapped file size, though it seems
like a useful concept.  Any quick pointers?

Thanks,

Jen
