IP Pool from Freeradius

Dear FreeRadius users, I need to implement IP Pool into FreeRadius because I have multiple PPPoE Server. Reading about "_ippool/_sqlippool" I've found many issues (for example a bug that assign double IP). Are there same problem with the new version of FreeRadius (3.x) ? I've not enough IP to split my IP pools into multiple PPPoE server. (example 33% IPs of my ALL IPs into 3 PPPoE server) Regards, Man.
