Hello Robin,

Berkeley DB's transaction capability uses locks to allow multiple
programs to read/write the database.  The need is documented in the
README.db file and there's also information in bogofilter-faq.html.

Typically this happens when one or more copies of bogofilter is writing
to the wordlist at the same as bogoutil is dumping the wordlist.  Add/
modify the lock count in the DB_CONFIG file (if already present), or
create a DB_CONFIG file with the needed count.

Also remember that google is your friend.  A search for 

  bogofilter +"lock table is out of available locks"

gives several relevant hits.

Regards,

David
