<div class=WordSection1>

<p class=MsoNormal>I’m running CentOS 5.5 with dhcp-3.0.5-23.el5.  I
have failover setup for these servers.  Each building has its own failover
pair and serve address to around 8 vlans.  I’m using tagged vlan
interfaces on the servers and not dhcp relay.  I’m monitoring the
service on these servers using a custom Nagios script utilizing dhcping.<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>Every so often the dhcpd process wedges.  When I check
the process status, the pid exists but the process isn’t running.  I
check the logs and don’t see any errors.  All that is shown is one
minute the dhcp server is handing out leases and the next it isn’t. 
I restart the service and all is fine but I would like to figure out why this
is happening.<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>I’ve checked this lists archives and the CentOS forum
archives as well as googled for this issue and found bumpkis.  Any idea
what’s happening or suggestions on how to debug this issue?<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>Thanks.<o:p></o:p></p>
