What protocol is the Server using? Keep-Alives are default in HTTP/1.1. If you wish to close a connection after each response, you can change this behavior on the server or have the BigIP include a "Connection: close" header via an iRule.
The "Action on Service Down" will continue to select a down member if the TCP connections on both sides of the proxy are still valid, i.e. a reset hasn't been issued by the server or client.
Setting the pool action to "Reject" will cause a reset packet to be sent to the client, forcing a new TCP connection to be established, and a new load-balancing decision to be made (unless there is a persistence record.)
Additionally, there is a difference between "Disabled" and "Offline"
Offline still selects an active connection, but will not honor a persistence record
Disabled will honor a persistence record as well as active TCP connections
