Hi all,

after the update I noticed that the error messages didn't go away for a
little time. Also seeing the high load and high kernel cpu usage I did some
changes to the /etc/fstab (adding noatime,nodiratime) to /var /home
partitions.
Also the dovecot -n now is like this:
auth_mechanisms = plain login
default_login_user = dovecot
disable_plaintext_auth = no
dotlock_use_excl = yes
mail_access_groups = mail
mail_fsync = never
mail_location = mbox:~/.:INBOX=/var/mail/%u
mmap_disable = yes
passdb {
  driver = pam
}
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem
userdb {
  driver = passwd
}


I see that for about 2-3 days now the error has gone away, and dovecot is
running ok,
but the high load is continually present, and I suspect of disk I/O latency.

Again thank you for your support.
