What about Dovecot's logs? Do you see e.g.:
master: Warning: service(auth): process_limit reached, client connections are being dropped
No, I see no such messages. The only recent messages from dovecot: master are from shutdowns and startups.
How many imap/pop3/smtpd processes do you typically have?
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@sbh16 ~]# ps -fwA |grep [d]ovecot dovecot 2562 2913 0 18:56 ? 00:00:00 dovecot/auth root 2913 1 0 Mar22 ? 00:00:05 /usr/local/sbin/dovecot dovecot 2914 2913 0 Mar22 ? 00:00:01 dovecot/anvil root 2915 2913 0 Mar22 ? 00:00:02 dovecot/log root 5702 2913 0 21:01 ? 00:00:00 dovecot/auth -w root 18333 2913 0 07:23 ? 00:00:01 dovecot/config dovecot 18459 2913 0 07:28 ? 00:00:00 dovecot/imap-login dovecot 18460 2913 0 07:28 ? 00:00:00 dovecot/imap-login mark 18462 2913 0 07:28 ? 00:00:01 dovecot/imap gpc 18463 2913 0 07:28 ? 00:00:00 dovecot/imap dovecot 24840 2913 0 11:39 ? 00:00:00 dovecot/imap-login mark 24841 2913 0 11:39 ? 00:00:00 dovecot/imap [root@sbh16 ~]#
One curious thing I noticed
[root@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@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.
