You probably have a huge bayes_seen like I did. You can safely delete 
this file. It's the bayes_toks that's the important one. You only need 
the bayes_seen data if you ever "unlearn" a message by calling sa-learn 
directly from the command line.

I hit this exact same problem yesterday, see earlier comments in this
