No, I see no such messages. The only recent messages from dovecot:
master are from shutdowns and startups.

3 to 5 postfix smtpd listeners
I think the following is fairly typical for dovecot (it listens on
pop3, pop3s, imap and imaps). I am essentially the only imap user and
it would be rare to have two concurrent pop3 connections.
[root at sbh16 ~]# ps -fwA |grep [d]ovecot

One curious thing I noticed
[root at sbh16 ~]# grep 16817 /var/log/maillog
Mar 26 06:22:58 sbh16 postfix/smtpd[16817]: warning: SASL: Connect to
private/auth failed: Resource temporarily unavailable
Mar 26 06:22:58 sbh16 postfix/smtpd[16817]: fatal: no SASL
authentication mechanisms
Mar 26 06:22:59 sbh16 postfix/master[25437]: warning: process
/usr/libexec/postfix/smtpd pid 16817 exit status 1
[root at sbh16 ~]#
I.e. the log goes back to March 21, and those 3 messages are the only
occurrences of that postfix/smtpd PID. The same is true for other
occurrences of the problem.
