[Bug 358589] [NEW] Segmentation fault during peer startup in failover configuration

Public bug reported:


I'm running redundant servers using failover peer mode in which both
daemons actively handle DHCP requests and share lease information.

Expected operation:

Under normal operating conditions, both daemons should start in any
order, synchronize lease information, and begin handling DHCP requests.

What actually happens:

Using the Jaunty DHCP server package (dhcp3-server 3.1.1-5ubuntu8), the
first daemon consistently starts up properly, but the second generally
throws a segmentation fault.  After several attempts, the second daemon
eventually starts up properly.  However, upon restart will resume the
pattern of throwing segmentation faults.  Once both daemons successfully
start up, they seem stable and perform as expected.

Release information:
