TMM core on HTTP response with steering action.
TMM cores trying to steer the existing connection. Traffic disrupted while tmm restarts.
HTTP profile is not attached to a PEM virtual server receiving the HTTP response. In this case, on receiving a connection request from the client, the BIG-IP system establishes server-side connection without waiting for the HTTP request from the client. Meanwhile, a steering policy got installed. The server responds with an HTTP request timeout message.
To avoid this issue, attach an HTTP profile to the PEM virtual server.
TMM no longer cores on HTTP response with steering action.
