That's... amusing. The internal DB-file open operation has
not returned a handle to use, yet errno is zero.

My question, too.

Who built the binary, and what variant of DB file handling is
being used? Could there have been a DB library update, or
corrupt files lying around?

Does it otherwise appear operational? Was it once-only, occasional,
or repeat-on-any-smtp-transport-attempt?
