求助 socket服务端 sun_pah被占用

  我写了个socket服务端异常退出了, 然后程序服务端程序重启后,服务无法创建,这个怎么解决? 请各位高手指点.
  我创建服务端的代码是:
  int _server = socket(AF_UNIX, SOCK_STREAM, 0);
   
  struct sockaddr_un sun;
sun.sun_family = AF_UNIX;
sprintf(sun.sun_path, "xiegh_test");


if (bind(_server, (struct sockaddr*)&sun, sizeof(sun)) == -1 || listen(_server, 5) == -1)
{
cout << "socket bind&listen failed" << endl;
return 0;
}

rm xiegh_test
