postfix and cyrus

[John Lederer]

I am running postfix with cyrus 2.1.2.

I ocasionally get the following error message in the log:

Apr  3 10:16:46 mail lmtpd[1983]: duplicate_mark: closing 
/var/lib/imap/deliverdb/deliver-b.db: DB_INCOMPLETE: Cache flush was 
unable to complete
Apr  3 10:16:46 mail lmtpd[2226]: duplicate_check: closing 
/var/lib/imap/deliverdb/deliver-b.db: DB_INCOMPLETE: Cache flush was 
unable to complete

I suspect that postifx is feeding cyrus faster than cyrus can take it.  
If that seems likely, is there a good way to throttle the flow?
