Is it possible that sb_filter.py and sb_mboxtrain.py run at the same time?
If so, that would be enough to cause problems, especially using Berkeley DB.

Download and install ZODB, change your config file to refer to it:

    [Storage]
    persistent_use_database: zodb
    ...

then retrain from scratch.

I don't recall what version you're running, but zodb is the default starting
with 1.1a2.  Depending how much older the version you're running is, you may
or may not find support for ZODB in the SpamBayes tool set.  I recommend you
update to 1.1a3.
