[Dovecot] Error: Maximum number of mail processes exceeded

[Antonio Casado Rodríguez]

Hello again, i changed "login_max_processes_count" to 1500 but with 1024 
process the error is the same:
dovecot: Nov 12 13:10:11 Error: Maximum number of mail processes exceeded
dovecot: Nov 12 13:10:11 Error: Maximum number of mail processes exceeded
dovecot: Nov 12 13:10:13 Error: Maximum number of mail processes exceeded
dovecot: Nov 12 13:10:18 Error: Maximum number of mail processes exceeded

Is there any limit in other place?

Thanks you!
