virtual server behavior

Ralph, this is by design. See Disabling a virtual server may not prevent a lower precedence virtual server from processing traffic

default settings do not allow a lower precedence virtual server to handle a request when a higher precedence virtual server is administratively disabled. This behavior is by design, and is controlled by the tm.continuematching db variable

And this one too: Overview of the 'tm.continuematching' db variable

Hope this helps,
