BTW, could you compress some of the data you put up on your FTP
site? The .mhonarc.db file is huge, and compressing it will make
download muck quicker.
Done. ftp://jab.org/db.tgz (It's still pretty huge.)
I will attempt the other diagnostics you suggested. I'd like to do
some more observation on the 2.3.0 archives as well, to get a better
characterization on whether the problem is deterministic or not.
PS You may want to wait until I've done another analysis before
cracking open the DB file... the preliminary results for 2.3.0
