Thanks for the answers.
Really, I didn't showed you basic informations.
I used the PostgreSQL 8.4. The server configuration was:
Processor: Intel Xeon Processor W3570 Quad Core Processor
Network Interface: Gigabit
HD: 12 x 1 TB (RAID1+0)
OS: Debian GNU/Linux, kernel 2.6.26-2-64
The client machines has similar configuration.
The error message was:
"Erro Conexão: A tentativa de conexão falhou."
"Erro Conexão: FATAL: connection limit exceeded for non-superusers"
I used the logs of my java application used to simulate the clients.
