Considering the many other projects using berkeley db successfully (we
have an internal svn repository with over 60Gb of data in a berkeley
4.2.52 database), this may be a problem with:
- the way cyrus uses the database
- bad DB_CONFIG

Of course, it could be also a bug in berkeley triggered by the way cyrus
uses it or any other combination of these factors.

Regarding BDB versions, 4.2.52 seems to be the best DB4 version
available, with perhaps 4.4.x being as good as (only time will tell).
