Is it after a certain load? Or after a certain time? That's an Exim complaint. The receiver didn't respond within Exim's time limit. The default is 5 minutes, you can change it with the "timeout" option on the transport (the one you've called mailbox_lmtpunix). So the question is why the lmtp service isn't returning soon enough. For that, you'll need to look at your system as a whole. _Perhaps_ upping prefork on the service entry in cyrus.conf will let things flow better by reducing the spike loads, perhaps it'll make things worse.
