Re: High Load average on NFS Spool - v.2.1.15 & 2.2.13
dont play net cop here
but since you want to try force your opinion down others throats heres

Can you please offer a suggestion on what is happening? The timeouts
to the imap server are frequent due to the load average.
Thank you.

High Load average on NFS Spool - v.2.1.15 & 2.2.13
I have two servers pointing to an NFS mounted mail spool with dovecot.
Since I recently switched from using Dovecot v1.X, I have been
experiencing high CPU use with the two Dovecot servers. I am not certain
why they are not well behaved. Here is the configuration information.
This configuration is currently running at a load average of 17.
/usr/sbin/dovecot -n
# 2.1.15: /etc/dovecot/dovecot.conf
# OS: Linux 3.10.54-server-2.mga3 i686 Mageia 3
base_dir = /var/run/dovecot/
disable_plaintext_auth = no
lock_method = dotlock
login_greeting = SpamZapper Email ready.
login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c
mail_debug = yes
mail_fsync = always
mail_location = maildir:~/Maildir
mail_nfs_index = yes
mail_nfs_storage = yes
mail_privileged_group = mail
mbox_lock_timeout = 15 mins
mmap_disable = yes
passdb {
driver = pam
}
protocols = imap pop3
service anvil {
client_limit = 203
process_limit = 1
}
service auth {
user = root
}
service imap-login {
chroot = login
client_limit = 10
user = dovecot
vsz_limit = 256 M
}
service pop3-login {
chroot = login
client_limit = 20
user = dovecot
}
ssl = no
syslog_facility = local2
userdb {
driver = passwd
}
verbose_proctitle = yes
protocol pop3 {
mail_max_userip_connections = 20
pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s
pop3_uidl_format = %08Xv%08Xu
}
protocol lda {
postmaster_address = postmas...@example.com
}
protocol imap {
mail_max_userip_connections = 10
}
And the other server which is currently running with a load average of 10.
dovecot -n
# 2.2.13: /etc/dovecot/dovecot.conf
doveconf: Warning: service anvil { client_limit=100 } is lower than
required under max. load (303)
