Since xCAT does not know whether the dhcpd (includes the leases file) has been configured, so in each starting of xcatd, the dhcpd is reconfigure with 'makedhcp -n and makedhcp -a".
You can try to work around it to set the setupdhcp attribute of service node to '0'.

Is there an option for disabling this feature? Our leases are already generated for the nodes, so each time the xcatd process is restarted it causes a 1+ hour outage for that service node due to the ~2500 compute nodes we have on each service node, and how slow the process of lease generation is.
