dovecot - Aug 2010 - Error: service(auth): child 2212 killed with signal 11

Hi,


Auth always crash (segfault) using vpopmail backend.

Any idea ?

vpopmail 5.5.0
os: ubuntu 10.04 on rackspace cloud

# dovecot -n

dovecot -n
# 2.0.1: /usr/local/etc/dovecot/dovecot.conf
# OS: Linux 2.6.35.1-rscloud x86_64 Ubuntu 10.04.1 LTS
auth_debug = yes
auth_mechanisms = plain login cram-md5
auth_verbose = yes
auth_verbose_passwords = plain
disable_plaintext_auth = no
first_valid_uid = 89
log_path = /var/log/dovecot/dovecot.log
mail_debug = yes
passdb {
   driver = vpopmail
}
protocols = imap pop3
service auth {
   unix_listener auth-userdb {
     group = vchkpw
     mode = 0600
     user = vpopmail
   }
   user = root
}
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem
userdb {
   driver = vpopmail
}
