no start of radiusd after reboot : mysql connection error

[mailinglists]

Hello,
I use freeradius-1.1.3-1.2.el5 and freeradius-mysql-1.1.3-1.2.el5. the 
mysql database (mysql-server-5.0.22-2.1.0.1) is hosted on a remote host 
(both centos5).
When I use /etc/init.d/radiusd as root it starts up correctly. But when 
the service is launched at boot time, I get this error-log :

I set a tcpdump on the mysql-server host, and during the boot of my freeradius server, I see no traffic comming from freeradius host.
There is no reject in the firewall.
I've tried to put the radius rc.d script in S99 to start it as late as possible, but nothing changes.
I also noticed that it doesen't seem to retry to connect to the database later. Or is it after a long time ?
Is this a bug ?
Where is the retry time configured (I cant try to set up to 5 seconds) ?

Thanks for answers

Laetitia.
