Default dovecot - increase login_max_processes_count

Hi, failed to send an email with smtp block error.

check of the logs showed the account had these errors
Code:
server dovecot: dovecot: All login processes are in use. You may need to increase login_max_processes_count
Code:
server dovecot: IMAP(mail@domain.co.uk): Inotify instance limit for user exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances
I have done a google and seems i need to edit one or all of following settings

Code:
login_process_per_connection = yes
login_processes_count = 3
login_max_processes_count = 128
login_max_connections = 256
this what dovecot.conf do i use and what is exact sysntax?

I found:

Code:
/etc/dovecot/dovecot.conf
and
/var/run/dovecot/dovecot.conf
Also tried

Code:
echo 256 > /proc/sys/fs/inotify/max_user_instances
thanks

Default I'm having the same issue

We get these errors on the email server every day. I increased the login max process once and it broke the email so I took it back.

Jun 25 15:23:39 dovecot: Warning: All login processes are in use. You may need to increase login_max_processes_count
Jun 25 15:28:40 dovecot: Warning: All login processes are in use. You may need to increase login_max_processes_count
Jun 25 15:33:41 dovecot: Warning: All login processes are in use. You may need to increase login_max_processes_count
Jun 25 15:36:33 imap-login: Panic: file priorityq.c: line 122 (priorityq_remove_idx): assertion failed: (idx < count)
Jun 25 15:36:33 dovecot: Error: child 27280 (login) killed with signal 6 (core dumps disabled) (ip=127.0.0.1)
Jun 25 15:38:42 dovecot: Warning: All login processes are in use. You may need to increase login_max_processes_count
Jun 25 15:43:43 dovecot: Warning: All login processes are in use. You may need to increase login_max_processes_count

How do I increase my login max processes with breaking my email server? am I being invaded by spammers or other people that would increase the logins? I have a large user base so this server needs to be able to handle the logins to the email server.

Thanks in advance
Kyle
