Since I'm using the vnd.dovecot.duplicate extension in my sieve script, we got the same error exactly three times, but only on Feb 11. We are using LMTP on a 4 node director+mailbox dual-instance setup with NFSv4.

No further errors on dovecot-error.log. The error did not reoccur yet and seems to be very rare.
This error happens when the dupes file has been locked for 10 seconds. I guess that user was delivered multiple mails at the same time and the delivery took a long time.. I made the error message somewhat better anyway: http://hg.dovecot.org/dovecot-2.1/rev/81ea622b6394
