Could not delete the hosts.

[Babasaheb]

Today i saw a strange issue. I upgraded my fog version from 0.28 to 0.31.
I have hardly cloned 500 machine from this server.
When i clicked on List All Hosts, it’s showing about 21,303 hosts, and it started pinging them
and finally browser goes in hang state.

Can you suggest me any alternate solution to delete this hosts, as even i cant move them to group and delete the group.
Our most of the work had stacked because of this.
