[Dovecot] IMAP goes down from time to time

[Juan Felipe Estrada]

Good afternoon again

I was thinking about the Dovecot upgrading so i´m doing this in the next 
hours. in the other hand here i show you the dovecot-ldap.conf file I 
think it has just the necessary options to bind the LDAP server.

/hosts = *********
base = ou=People,o=*****,o=******
ldap_version = 3
auth_bind = yes
auth_bind_userdn = uid=%u,ou=People,o=******,o=******

/About the dovecot.conf should I use some login options as 
/login_process_per_connection = yes  /or  /login_processes_count = 1/?

For now thanks so much for the help i´ll inform about the new version 
installation
