Sangeetha Hariharan commented on CLOUDSTACK-2428: ------------------------------------------------- Tested with build from 4.3 Set up - Advanced zone set up with 2 Xenserver 6.2 hosts. I had few hourly snapshots that are scheduled. Shutdown master host. Both the host continue to show up as being in "Up" state: I see the following exception in the logs: Both hosts show the status as being "UP" in the cloud platform and following exception is seen:
