Oh, you're using kqueue.  I didn't know OpenBSD eventually grew support
for it.

FWIW, I've stopped using dovecot's kqueue code quite some time ago
because it would leak one fd almost every login, leading to the kind of
situation you experience.  I wish I had the time to debug that, but
unfortunately...
