MYSQL and FreeRadius

Hi I have currently setup FreeRadius 1.0.4 with ldap authentication and authorization as well as mysql authorization and its all working fine. The problem exists when I restart the server, freeradius starts on boot but it fails in connecting to the MYSQL server. If I then shutdown the service and start it again it works fine. I have move the boot order to be S99 but it still fails. The MYSQL server is on a seperate server, so I am wondering whether the ports are blocked until startup is complete, if this is the case How can I get round this??? I am using Fedora Core 4... Has anyone else had this problem??? thanks diniz
