DBERROR db3: lockers

[Scott Russell]

Greets.

While testing Cyrus IMAPd 2.1.9 I noticed these errors in my logs:

  Sep 11 17:23:55 ogg lmtpd[773]: DBERROR db3: 16 lockers
  Sep 11 17:23:55 ogg lmtpd[1409]: DBERROR db3: 17 lockers
  Sep 11 17:23:56 ogg lmtpd[1508]: DBERROR db3: 9 lockers
  Sep 11 17:23:56 ogg lmtpd[776]: DBERROR db3: 9 lockers
  ...
  Sep 12 09:54:33 ogg ctl_deliver[5430]: DBERROR db3: 5 lockers

I've seen some discussion about them on the list and figured I would
report my case as well. I didn't notice them when I was load testing
but found them today during a log review. So far I cannot replicate
them again. Any suggestions as to what to do or check are welcome. 

When testing I was using postfix 1.1.7 and smtp-source with the
following command (with various size and message numbers):

  smtp-source -c -l 30000 -t testacct at localhost -s 5 \
  -m 400 localhost
