      Testing the same bogus error with postscreen:

      > Does not reproduce on Ubuntu 9.10-server with the default Berkeley DB 4.7.
      Also not on Fedora Core 11 with the default Berkeley DB 4.7.25.

      > address_verify_cache_cleanup_interval = 0
      > postscreen_cache_cleanup_interval = 0
      > This can't be the same bug as discussed last month with "close
      > database after fork", because verify(8) does not fork. Also, Postfix
      > does not close the same database twice (I wipe the database handle
      > after close to prevent that from happening).
