[Dovecot] Waiting for authentication process to respond..

Hmm... I'm seeing a lot of:

• OK Waiting for authentication process to respond..
• OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH=GSSAPI AUTH=GSS-SPNEGO] Welcome to the IFM Dovecot Mail Server.

when IMAP clients connect to our server (ie that "Waiting for.." message before the login OK message).

Now, most clients seems to handle this extra information message just fine, but it still is annoying me. It doesn't appear all the time, but pretty often...

What can I adjust/fix in order to make it go away?

System:

Sun Fire X4240, 32GB RAM, 2 Quad-Core Opteron 2356 Solaris 10 Update 9 Dovecot 2.0.13 Maildir on local (ZFS) storage

Normally about 200-300 unique users connected, around 400-600 mail processes.
