Failover xid mismatch errors

I am running DHCPD 4.0.2b2 and I am getting lots of errors like:

server dhcpd: [ID 702911] bind update on got ack from dhcp: xid mismatch.

I found this comment from David Hankins in 2008:

I just wanted to know has the "at some point" arrived yet :-)

Is there an option to turn this error line off?
