<br>
I am still playing around with the problem that an 3.0.5 Dhcpd (that

now failover), <br>
isn't working correctly if I make it to a primary. <br>
<br>
I checked the logfiles of the last tests and disovered that it does not
<br>
work any more <br>
after serving exactly 80 machines. <br>
After that no new DHCPACK is recorded and the machines are not getting
an <br>
address <br>
<br>
can somebody tell me why please <br>

<br>
Well, let's see... <br>
<br>
<br>
- no logs <br>
- no configuration <br>
- no lease database <br>

Hi Jeffrey!<br>
<br>
Sorry - I didn't include more information, because the same
configuration was working before<br>
switching to Cent OS 5.2 so I do not expect that it is wrong - I
thought somebody can give me<br>
a hint like "check the ulimits for this or for that ..." - Sorry my
fault here are the informations:<br>
<br>
<b>System: </b><br>
Cent OS 5.2, ISC Dhcpd 3.0.5 with paranoia and ldap patch. Started with:<br>

Logs (from the last test):<br>
The Dhcpd serves all clients until the count of the leases reaches 80 <br>
(counted with: grep "hardware" dhcpd.leases | cut -d" " -f5 | sort -u|
wc -l)<br>
(Dec 3 08:04:48) then you get only DHCPACK for Dhcp Refreshes or<br>
when you leases<br>
