The database contains message-IDs of already delivered messages.  It  
is used to suppress duplicate messages to the same users.  Removing  
the database may allow some (small) number of duplicates to be  
delivered.  You should have a line like:

EVENTS {
         # expire messages and deliver.db entries
         delprune        cmd="cyr_expire -E 1" at=0300
}

in your cyrus.conf file.  This ought to keep deliver.db from growing  
out of bounds.  If deliver.db has become corrupt, simply deleting it  
is a good plan.
