This is Info message, so it should be accompanied with
Error/Fatal/Panic. Most likely this one:

What happens is:

1. imap/pop3-login process authenticates user via auth process
successfully and forwards the connection to imap/pop3 process.

2. imap/pop3 process asks auth process to verify that the user is
authenticated and asks for userdb info.

[Somewhere before this imap/pop3-login either died or for some reason
disconnected from auth process.]

3. Auth process notices that the login process is gone and fails with
this error.

It shouldn't be happening, so it's a bug. What kind of service settings
do you have? Could you post "doveconf -n service" output?

Probably because of NFS caching.
