crash when processing TCP traffic. This vulnerability affects TMM via
a virtual server configured with TCP profile. Traffic processing is
disrupted while Traffic Management Microkernel (TMM) restarts. If the
affected BIG-IP system is configured to be part of a device group, it
will trigger a failover to the peer device. (CVE-2017-6162)
