call connects drop drasticaly when speed increases !!!

[asterisk_at_my_risk]

Hello

i am having a very strange issue when i do a auto dial with vicidial

at at a speed of 1.5 very things go fine but as i increase my speed to

3 agent do get very very few calls there IDEAL time increases to 7 to 8 minutes

my vicidial version is 2.0.3
asterisk 1.2.17
linux distro 2.6.17.11
system load is 0.8

its a multi server setup with one server on vicidial/asterisk and one on
db

config for both server is

2 GB RAM
quad core 2.0 Ghz
2MB L2 cache

system load at time when we increase speed seems to be pretty ok

less than 1 on a quad core



any clues will be of great help

i am using fedora core 6 and my.cnf file is default now can this issue be linked with max-conn as i am not seeing any error on my sip trunk

here is my.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

[mysql.server]
user=mysql
basedir=/var/lib

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid


how can i increase my max conn for my mysql

version: 5.0.22

Have you actually see connection refusals?

when you do a "mysqladmin processlist" how many connections do you see on average?

show full processlist
