That's a rather strange looking dovecot -n. You have every service listed there with name setting. That's not normal. And of course Raspberrypi .. wonder if it has something to do with it.

Yeah. Also get a list of "ps auxw" output. straceing some processes (dovecot, imap-login) might be helpful too.
