There are only 5 users surfing my website, and I suffer from too many connection problem. I use freebsd and mysql-server-4.0.24 with vBulletin.

Here is my my.cnf file:
[client]
port=3306
socket=/tmp/mysql.sock

[mysqld]
port=3306
socket=/tmp/mysql.sock

[mysql]
no-auto-rehash
set-variable = connect_timeout=12
set-variable = max_connections=1000
#mysql.allow_persistent=Off

Is there anything wrong with my configuration?

Any suggestion is appreciated!
