Any other way you want me to try and debug this? I'm ignorant in regards to kevent. I do note that the kevent manpage on NetBSD notes:
EV_DELETE Removes the event from the kqueue. Events which are attached to file descriptors are automatically deleted on the last close of the descriptor.
Maybe dovecot-auth is closing the fh before calling io_loop_handle_remove()?
