Hi !

> Run a tcpdump on one of your servers, maybe you got clients where the 'secs' field of the DHCPDISCOVER header is greater than 3 (as specified by "load balance max seconds 3"). If that's the case, the load-balancing is disabled and both servers will offer an IP, which will cause a 'is duplicate' message.

Yes, I guess that it is the same problem. Have rebuild with your patch, 
but did you also do some config change in dhcpd.conf ?
