Description

The input validation that triggers:

$input_errors[] = gettext("This entry cannot be deleted because it is still referenced by a CARP IP with the description") . " {$vip['descr']}.";

prevents the deletion of any IP alias within the subnet of a defined CARP IP. It's intended to keep you from shooting yourself in the foot and breaking your CARP on that subnet, but it should only prohibit deleting the last IP alias within a CARP IP's subnet as it's perfectly valid to delete any additional IP aliases within that subnet.

It can be worked around by editing the IP alias VIP and changing its IP subnet or subnet mask, then deleting the IP alias, as that same input validation is not done upon editing.
