i had this problem too, i change to use kqueue to poll (notify), then
the problem is solved
(all connection tls/ssl/plain)

if you want use poll, you need use "--with-notify=pool" for configure script

on my system(openbsd), if i do not use "--with-notify" flag,
dovecot will use kqueue for notify by default
and use poll for ioloop by default

shell$> dovecot --build-options
Build options: ioloop=poll ipv6 openssl
SQL drivers: mysql
Passdb: bsdauth checkpassword passwd passwd-file sql
Userdb: checkpassword passwd prefetch passwd-file sql static
