In my experience BDB 4.1 has always been subject to "spontaneous"
corruption: Instead of doing what you did (drastic to say the least) you
could have run 'db_recover -c' (or db_recover-4.1 or whatever it is on
your Fedora box) after stopping the server. That would have got you your
database back again.
Only at OL 2.2>~14 and patched BDB 4.2.52 have I experienced total
absence of corruption over extended periods (months).
