AnalysisBecause the load generator is performing so well, the packets are particularly fast and the server responds particularly quickly, causing the port of the load generator's machine to be fully occupied before the timeout is reached. When all is full, the above error will occur. You can see that many ports are open by executing the netstat–na command. Therefore, the time out of TCP is adjusted. That is, when the last port has not been used, there is already a port in front of it being released.
a successful solution:In the load generator's registry hkey_local_machine\system\currentcontrolset\services\tcpip\parameters, There are two key values: TcpTimedWaitDelayMaxUserPort1, here the TcpTimedWaitDelay default value should be 30s, so here, turn this value to 5s (adjust as needed). 2, you can also turn the MaxUserPort (if this value is not the maximum value).

Try to modify the registry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, there are the following two key values: TcpTimedWaitDelay---1 MaxUserPort----65534-Port wait time is small and the maximum available port is adjusted
