Just ran into this with fully up-to-date iRedMail and iRedAdmin-Pro. We use SQL, Apache.

Customer called having gotten a "too many logins" message. I saw the message in /var/log/dovecot.log as well.

Sep 15 14:18:35 imap(XX@XXXXXX.com): Warning: Inotify instance limit for user 2000 (UID vmail) exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances

Need a clean way to address this.

Please append settings below in /etc/sysctl.conf:

fs.inotify.max_user_instances=256
fs.inotify.max_user_watches=256

Then run command 'sysctl -a' to load new settings. it will increase max_user_instances.

To load 'sysctl.conf' new settings I used 'sysctl -p' because 'sysctl -a' only list current config.
