Descriptions

On BIG-IP 14.0.0-14.1.0.1, 13.0.0-13.1.1.4, and 12.1.0-12.1.4, the Traffic Management Microkernel (TMM) may restart when a virtual server has an HTTP/2 profile with Application Layer Protocol Negotiation (ALPN) enabled and it processes traffic where the ALPN extension size is zero.

En BIG-IP versiones desde 14.0.0.0 hasta la 14.1.0.1.1.4, desde la 13.0.0 hasta la 13.1.1.1.4, y desde la 12.1.0 hasta la 12.1.4, el Traffic Management Microkernel (TMM) puede reiniciarse cuando un servidor virtual tiene un perfil HTTP/2 con Application Layer Protocol Negotiation (ALPN) habilitado y procesa el tráfico en el caso de que el tamaño de la extensión ALPN sea cero.
