I think I figured out what is going on.  I had noticed that
the problem starts when the bayes_toks file gets to be about
5 meg.  I think that what happens is with the larger
database file, when autolearn writes to the file, it
basically takes too long, and on a server with as much
incoming email as mine, it basically runs into a conflict.
Since sa-learn will continue to run after a file access
error, rather than abort, this probably accounts for my
problem.

I've decided to experiment by limiting the size of the
bayes_toks file, with this entry to local.cf:

bayes_expiry_max_db_size 90000

The default entry for this is 150000, which basically can
allow the database to grow to 8 megs.

I'll see if this resolves the problem.
