First of all, don't put the bayes databases in that dir if you are using
a tmpfs.  That will cause it to be lost if you kick your server.

Second, the bdb bayes storage module is known to have locking issues.
It uses flat file locking which doesn't work so well on busy servers.

The spamassassin guys released 3.1.0rc1 this morning, which among other
things has FAR better bayes SQL support.  Pgsql is 7x faster
(translation: usable) and the mysql stuff is 2x faster.

I recommend that you go to 3.1.0 and use a sql database for bayes, it
works a bit better.  You can use mysql or pgsql.  If you already have
one up and running then use it otherwise mysql is going to be faster.  I
use pgsql because mysql doesn't cut it for my other db needs, and don't
want to run both.
