I meant in general, but more specifically in my case trying HA, it seems to happen quite a lot.  I've seen my two HA server spontaneously decide to switch DHCP from one host to the other, upon which, all the DHCP DNS entries on the old host seem to disappear causing me a cascading set of headaches when my computers stop being able to find one another.  Also it seems that when the DHCP server is running on one of the hosts reverse DNS mappings get correctly updated on both hosts, but when running DHCP on the other server, one of the DNS servers stops getting reverse DNS entries, even though I can see it getting zone update notifications.
