If you delete the dict-server socket and start Dovecot again, does it
then show anything else except the "Auth process died" message?

I guess it doesn't figure out that master has died and doesn't try to
restart it.

It sounds like dovecot-auth process dies with exit status 0. See if it
logs anything with the attached patch.
