Which Berkeley DB is best?

[Aidan Evans]

  We're using Berkeley DB 4.0.14 for deliver.db and tls_sessions.db and for
the second time in a couple of weeks both of these databases are
non-functional because of "Lock table is out of available locker entries".

  This error may be caused by a bug that is fixed as described in
"http://www.openldap.org/its/index.cgi/Software%20Bugs?id=2040".  However,
the patch appears to be against a newer version of the code than we are
running, so I'm just a little bit concerned about simply patching and
hoping for the best.  As an alternative I was considering downgrading to
a version 3 Berkeley DB.

  Is there any consensus as to the "best" version of Berkeley DB to use
with Cyrus 2.1.9 on RedHat Linux 7.2.
