dovecot - Sep 2012 - Can`t get over 1024 processes

Hello,

I have configuration question. Running FreeBSD 9.0 / AMD64 / Dovecot 
2.1.8 version and cannot get over 1024 processes. I`ve increased 
process_limit in imap and pop3 and still have messages in syslog like: 
maxproc limit exceeded by uid 89, please see tuning(7) and login.conf(5).
Did I forget to increase some other value? System values are higher - 
kern.maxprocperuid: 8192 and kern.maxproc: 12288

I`d like to have more secure configuration > one process to one connection.

Thanks for help.

Tomas

That message comes from the kernel. Dovecot doesn't use login.conf. You need
to set ulimit -u manually (= in init.d script) before starting Dovecot.
