Severity: 3-Major


After a rate limit is triggered and released, the virtual server status in the GUI remains as 'unavailable'. The virtual server resumes accepting new connections while the GUI shows the virtual server is unavailable.


Actual virtual server status is not reflected in GUI.


-- The virtual server has a source address list configured. -- Address lists define more than one address. -- The connections are over the rate limit, and the virtual server status is marked unavailable. -- The number of connections falls below the limit.


If the deployment design allows, you can use either of the following workarounds: -- Remove the source address list from the virtual server. -- Have a single address in the source address list.
