dovecot - May 2006 - Errors in dovecot 1 beta7

Hi,
I just installed dovecot 1.0 beta 7 and I have these errors:

I run dovecot in CentOS 4.3 using openldap/nss_ldap/nscd

The problem get resolved when I restart dovecot. Is this a problem in 
dovecot or in nss_ldap/nscd?
How can I debug even further?

Many thanks
Oliver

I'd recommend not using nss_ldap but using Dovecot's LDAP support
directly.

I see these errors talso:
May  6 09:02:10 mail dovecot: pop3-login: Disconnected: Inactivity: 
rip=::ffff:xx.xx.xx.13, lip=::ffff:xx.xx.xx.1

May  6 09:02:13 mail dovecot: pop3-login: Login: user=<user1>, 
method=PLAIN, rip=::ffff:xx.xx.xx.10, lip=::ffff:xx.xx.xx.1

What does "Master request 21566.1 not found" means?

Many thanks
