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>

What's the other server logging ? Are the two servers communicating properly ? Is the other server handing out leases ?<br><font color="#888888">
