求助各位大哥,客户机有时无法从dhcp服务器获得IP问题.

系统:red hat 9.0
安装dhcp  rpm包:dhcp-3.0pl1-23
有时客户机无法获得IP,有时又可以,得不到IP时日志如下:

一直不断重复dhcp的四个过程,按理DHCPACK后dhcp会话已经结束,客户机应该获得IP地址,但为什么服务器又发现了客户机的DHCPDISCOVER,服务器和客户机之间又重新开始dhcp会话了呢,望高手指点.

配置文件如下:
#ddns-update-style interim;
#ddns-update-style ad-hoc;
ddns-update-style none;
#ignore client-updates;
default-lease-time 1200;
max-lease-time 3600;
option subnet-mask 255.255.254.0;
#option domain-name-servers 219.237.16.66;
option domain-name-servers 10.10.10.33;
option routers 10.10.10.254;

subnet 10.10.10.0 netmask 255.255.254.0 {
        range  10.10.10.34 10.10.10.250;
        range  10.10.11.1 10.10.11.250;
}
#subnet 219.239.14.128 netmask 255.255.255.224 {}
#subnet 172.16.0.0 netmask 255.255.255.224 {}

没人帮我吗,我又查了些资料,客户机可以拒绝服务器分配的IP地址,但如果客户机拒绝这个地址会发送DHCPDECLINE包(日志中没有),然后才重发DHCPDISCOVER包.谁能帮帮我啊,
