[Dovecot] Fatal: imap-login: io_loop_handle_add: epoll_ctl(1, 4): Operation not permitted

[Jérôme Blanc]

Hello, 

I'am following the beginning tutorial on the Wiki, but actually, I
can't even start the server correctly so far. The imap-login child dies
immediately. What I can guess from the log is that it tries some
unpermietted operations on some files but I can't find out which files
are concerned.

Google is not my friend at all either on this matter. How can I know
which files are concerned ?

Some infos that might help : 

[root at Aries ~]# dovecot -n
# 1.1.6: /etc/dovecot.conf
# OS: Linux 2.6.27.14-server-1mnb i686 Mandriva Linux release 2009.0
(Official) for i586 ext3 ssl_cert_file: /etc/pki/tls/certs/dovecot.pem
ssl_key_file: /etc/pki/tls/private/dovecot.pem
login_dir: /var/run/dovecot/login
login_executable: /usr/lib/dovecot/imap-login
mail_privileged_group: mail
mail_location: maildir:/var/mail/%n
auth default:
  passdb:
    driver: passwd-file
    args: /etc/passwd.dovecot
  userdb:
    driver: passwd

[root at Aries ~]# ls -ld /var/mail
drwxrwx--x 3 root mail 4096 2009-03-10 18:06 /var/mail/

[root at Aries ~]# service dovecot start

And here is what I get in the /var/log/syslog file : 

Mar 10 20:00:47 aries dovecot: Dovecot v1.1.6 starting up

Mar 10 20:00:48 aries dovecot: Fatal: imap-login: io_loop_handle_add:
