Windows 10: Not able to established more than 65532 TCP/IP Socket Connection in windows 10 after...

After 65532 TCP/IP Socket Connections in Windows 10, select returning -1.



WSAGetLastError is returning Error 10055 - No Buffer Space Available.


Can Windows support more than 65532 TCP/IP Socket Connection or not ?


I have modified the registry:

[HKEY_LOCAL_MACHINE \System \CurrentControlSet \Services \Tcpip \Parameters]
TcpNumConnections = 0x00fffffe Default = 16,777,214

MaxUserPort = 5000 Default = 5000, Max = 65534

TcpMaxDataRetransmissions = 5

TcpTimedWaitDelay = 30

TcpWindowSize = 64512



Thank You,
