tmm might core when rate-limiting is configured on a virtual server.
Traffic disrupted while tmm restarts.
This occurs on a virtual server with rate-limiting enabled and unexpected filter operations that send LB selection after connection is in progress. This might also occur with an iRule that behaves similarly, for example, issuing an LB command after a TCP::release.
The connection is terminated and tmm core no longer occurs.
