Hello

    I was unable to delete a POD & the "Physical Network 1" from a basic zone from the CS MGMT UI v4.1.1, therefore I had to manually update the "removed" & "state" coloumns for the CS DB table "physical_network" id 205.

After which the "Network" tab in CS MGMT UI displays "Error" and when we try to access a Project via Project View, the following error is displayed:

=====================
Running the command "listNetworks" via cloudmonkey provides me with a
"HTTP Error 530:" error.

Any thoughts on how this error could be resolved?

Thomas
