TMM crashed while deleting connections.
Traffic is disrupted while TMM restarts.
1.There are a high volume of connections remaining (those connections born from a virtual server which has iRule with "after XXX -periodic" iRule command) and connections are deleted. 2. A huge number of DNS requests are sent from the same source IP/port to a datagram_LB enabled UDP listener, which results in a huge number of flows in the same bucket and connections are deleted.
