<div>Hello </div>
<div><br>
</div>
<div>I'm using ISC DHCPv4 Server 4.2.2 for docsis purpose.</div>
<div>We are having problem with some CM-s (not all) , remains in state init(d) , do not get ip address.</div>
<div><br>
</div>
<div>From the logs we see that the modem gets ip address and release it, and this ip is assigned to another modem.</div>
<div>But the modem still request the old ip address.</div>
<div>The problem happens every week on tuesday.</div>
<div><br>
</div>
<div>Some critical logs : </div>
<div><br>
</div>
<div><i>Aug 22 10:23:48 dhcp2 dhcpd: Received DHCPv4 packet without client-id option and empty hlen field.</i></div>
<div><i>Aug 22 10:23:48 dhcp2 dhcpd: Impossible condition at dhcpleasequery.c:492.</i></div>
<div><i>Aug 22 10:23:48 dhcp2 dhcpd: DHCPDISCOVER from 5c:35:3b:08:93:44 via 10.94.224.1</i></div>
<div><i>Aug 22 10:23:48 dhcp2 dhcpd: ICMP Echo reply while lease 10.94.246.229 valid.</i></div>
<div><i>Aug 22 10:23:48 dhcp2 dhcpd: Abandoning IP address 10.94.246.229: pinged before offer</i></div>
<div><br>
</div>
<div><br>
</div>
<div>The problem is fixed after reseting all connections between cm-cmts or if we assign ip address statically.</div>
<div><br>
</div>
<div>It looks like dhcp lease file do not keep the records.</div>
<div>It's very strange problem. </div>
<div><br>
</div>
<div><br>
</div>
<div>Before that i use version 3.5.1 and we don't have any problem.</div>
<div><br>
</div>
<div><br>
</div>
<div>Thanks in advance , </div>
