dovecot - May 2005 - Dovecot auth process died because of Socket operation on non-socket

Hi,

I'm having problems setting up a dovecot1.0 stable on a Debian-amd64 
server. The process dies with the following message:

May 28 15:13:46 rouge dovecot: Dovecot v1.0-stable starting up
May 28 15:13:47 rouge dovecot: Login process died too early - shutting down
May 28 15:13:47 rouge dovecot: pop3-login: fd_send(-1) failed: Socket 
operation on non-socket
May 28 15:13:47 rouge dovecot: pop3-login: fd_send(-1) failed: Socket 
operation on non-socket
May 28 15:13:47 rouge dovecot: auth(default): accept() failed: Socket 
operation on non-socket
May 28 15:13:47 rouge dovecot: child 15116 (auth) returned error 89
May 28 15:13:47 rouge dovecot: child 15117 (login) returned error 89
May 28 15:13:47 rouge dovecot: child 15118 (login) returned error 89

Attached is the strace of the dovecot process, I don't know if this is 
relevant but I can provide any needed information.

The config file is like this:

protocols = imap imaps pop3 pop3s
ssl_disable = no
ssl_cert_file = /etc/ssl/certs/pop-imap-zamok.pem
ssl_key_file = /etc/ssl/private/pop-imap-zamok.pem
disable_plaintext_auth = no
login_processes_count = 6
mail_extra_groups = mail
default_mail_env = mbox:~/Mail/:INBOX=/var/mail/%u
protocol imap {
}
protocol pop3 {
}
auth_verbose = yes
auth_debug = yes
auth default {
   mechanisms = plain
   passdb = pam
   userdb = passwd
   user = root
}


Can anybody help me with this issue ?

Thank's in advance !

Could anyone help me with this issue ? I've tried several things but 
none worked. Dovecot0.99 works fine one the same machine with the same 
configuration (in dovecot0.99 format).

When I launch /usr/sbin/dovecot on the command line, I have the 
following logs, and the auth process dies immediatly:

May 28 16:01:07 rouge dovecot: Dovecot v1.0-stable starting up
May 28 16:01:08 rouge dovecot: Login process died too early - shutting down
May 28 16:01:08 rouge dovecot: auth(default): accept() failed: Socket 
operation on non-socket
May 28 16:01:08 rouge dovecot: child 21099 (auth) returned error 89

But strangely, when I launch /usr/sbin/dovecot -F on the command line, 
to make dovecot run in the foreground, then everything works perfectly 
and I'm able to login !

For now I've got no idea of what could explain this behaviour.


Thank's for any hint,

I think the problem is here. You should not leave these two blocks empty
as they are used to override ports dovecot listens to and you have
nothing there e.g.

protocol imap {
  listen = 127.0.0.1:14300
}

I'd suggest that you comment them out.

Thanks, Tero

Looks like Dovecot's master process gives wrong file descriptors to 
auth/login processes. I can't really think of why.. Unless libc or 
something does something strange in the middle.

The strace you sent doesn't help much because Dovecot forks and the 
strace ends there. Give -f option to it and send it again?
