My setting is as below: # # tcp_keepalive_intvl: The time (in seconds) between individual keepalive # probes. # Optional DTM_TCP_KEEPALIVE_INTVL=1
# # tcp_keepalive_probes: The maximum number of keepalive probes TCP should # send before dropping the connection. # Optional DTM_TCP_KEEPALIVE_PROBES=2 SO it needs two second for controller detect that payload has been shutdown? But in my test, this time is less than 2 second. Thanks.
