Nicholas, I'm fairly certain that the issue is being caused by dovecot performing a chroot prior to initializing its epoll handle. (On both native SmartOS and LX, epoll is implemented in terms of /dev/poll.) Could you look to see if there is a configuration option for chroot which you could temporarily disable to confirm the theory?
