[FUG-BR] maxproc limit uid 89, tuning qmail

[Joel Cappellesso]

Ola Pessoal,

May 17 09:22:21 avalon kernel: maxproc limit exceeded by uid 89,
please see tuning(7) and login.conf(5).
May 17 09:22:50 avalon last message repeated 9 times

meu login.conf o default está:


default:\
 ....
        :maxproc=unlimited:\
 ....

Não deveria estar sem limite .

Ou ele utiliza:

kern.maxproc: 6164
kern.maxprocperuid: 5547

Estou aumentando agora:
 sysctl kern.maxprocperuid=8547
kern.maxprocperuid: 5547 -> 8547
para teste.

Para melhorar a performance adicionei no arquivo : /boot/loader.conf
kern.ipc.nsfbufs="79872"                # Set the number of sendfile(2) bufs

Isso já melhorou o número de mensagens entregues ao mesmo tempo. Mas
ainda não ficou legal, não passa das 40 simultâneos.

Alguem tem alguma dica para melhorar a performance do qmail?
