Buenas a todos,

Alguna idea de como vaciar el buffer de TCP con Sockets. Tengo un ClientSocket que se intenta conectar a un ServerSockets cuando pierde conexión con este, La idea es si el SocketServer está conectado entonces me conecto en cuanto el ServerSocket se desconecta activo un timer para verificar cada cierto tiempo si el Server socket se ha vuelto a conectar y entonces me conecto, el problema es que cuando el cliente está mucho tiempo sin poder conectar con el ServerSocket, me genera un error :

Windows socket error: No se puede ejecutar la operación en un socket ya que el sistema no tiene suficiente espacio en buffer o porque la cola estaba llena(10055) on Api connect.

Me imagina que es que el buffer se llena de todos los intentos que hace para conectarse pero no se como poder solucionar el error. ¿Alguna idea?

Muchas gracias de antemano

un saludo

Jorge
