Tmm crashes when running tcpdump.
Traffic disrupted while tmm restarts.
1. A virtual server references another virtual server with an iRule 2. The destination virtual server has an iRule with reject inside FLOW_INIT 3. Use tcpdump while hitting the reject rule
Use either remote tcpdump or avoid using reject rule in FLOW_INIT.
Tmm no longer crashes in this scenario.
