I did find the hash database, they were in /var/spool/dspam/data

I put dspam back in my mail delivery path (postfix delivers to dspam 
delivers to dovecot), deleted the has files for each individual user and 
dspam has now stayed up for the last three hours.

So I am concluding that it is corrupted hash files.

I might look at migrating to one of the other drivers which use a proper 
database,
