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.
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
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?
