TLS connections through a virtual server with an SSL persistence profile attached may intermittently. A network trace will show the BIG-IP sending malformed TLS records to the server, typically resulting in the connection being closed/reset (a closer analysis reveals that the malformed records sent to the server were parts of the data received from the server).


Connections impacted by this occurrence will fail.
