Ive dont believe I've  seen this and I've had dovecot running for months
on FreeBSD with pam authentication. Perhaps that indicates it could be a
Fedora thing?

Never seen this either. But I use maildir, so that could be related too, I

Thought about using a different version (newer, or even older) of dovecot
and seeing if that makes the problem go away.
