I get the same problem with rc15, except that in 1.0.beta8, the error
would appear just once.  In rc15, it repeats once/second.  I guess rc15
restarts dovecot-auth if it dies?

Here are my non-default dovecot.conf (1.0.rc15) settings:

disable_plaintext_auth = no
ssl_disable = yes
protocol imap {
  mail_plugins = dspam
  mail_plugin_dir = /usr/lib/dovecot/imap
}
protocol lda {
  mail_plugins = cmusieve
  sendmail_path = /usr/sbin/sendmail
}
auth_cache_size = 64
# 4 hours
auth_cache_ttl = 14400
auth default {
  mechanisms = plain
  passdb pam {
    args = cache_key=%u%r dovecot
  }
  userdb passwd {
  }
  user = root
}

This is on Solaris 10U2/x86.
