Are you sure your dhcpd has the right to wright to the dhcpd.leases-file?
Is it writing a ~ version during the time the daemon is running? Maybe in your config is something odd that disallow writing to the dhcpd.leases-file?

Did you send your omapi-updates to both of your servers (like you have to)? Or only to one of them and after the restart they take the leasefile from the other server without th hostentries?
