[Dovecot] auth(default): vmysql: sql error[3]: MySQL server has gone away

[Jordi Prats]

Hi all,
I'm facing this error:

dovecot: auth(default): vmysql: sql error[3]: MySQL server has gone away

I've been reading this list archives and seems to be a resolved issue
(back to 2005), so dovecot should just reconnect but it does not so.
I'm using dovecot 1.1.3 with vpopmail 5.4.25 with this configuration:

# 1.1.3: /usr/local/etc/dovecot.conf
listen: *:143
ssl_disable: yes
disable_plaintext_auth: no
login_dir: /usr/local/var/run/dovecot/login
login_executable: /usr/local/libexec/dovecot/imap-login
verbose_proctitle: yes
first_valid_uid: 89
last_valid_uid: 89
mail_location: maildir:/home/vpopmail/domains/%d/%n/Maildir
auth default:
  passdb:
    driver: vpopmail
  userdb:
    driver: vpopmail


Any ideas?

Thanks you!
