May 23 16:16:17 nadrdir02 dhcpd: failover peer dhcp-failover: I move
from normal to communications-interrupted
May 23 16:16:37 nadrdir02 dhcpd: failover: link startup timeout

That they go into communications interrupted when they lose contact is
fine, but the problem is that they never reestablishes contact. I have
to restart both servers manually to get them into the "Normal" state
again. Since the problem is solved by restarting the servers manually,
it's evident that the network problem isn't there anymore. So my
question is why they don't try to reestablish contact?

Both servers uses a timeserver to synchronize their clocks and I have
verfied that they don't differ. They are running Debian Sarge with the
latest DHCP version (isc-dhcpd-V3.0.5) compiled from the sources at
www.isc.org. The servers are running as Guests on two different VmWare
ESX 3.0 hosts.

Any help would be very appreciated!
