Due to a known issue, BIG-IP may create multiple connections for packets that should belong to a single flow. These connections will stay in the connection table until the idle timeout is reached. These connections can be used for forwarding the traffic.
This might result in packets from the client being handled by one flow and packets from the server being handled by a different flow.
BIG-IP may create multiple connections for packets that should belong to a single flow when both following conditions are true: - Packets are coming at a very high rate from the network. - Flow handling these packets is torn down.
