hi ,   There is a debug in ddns3-client.While the ddns3-client run for several days,there will be a few ddns3-client pids.I track the code,and find it because of the recv.It run to the recv line and do not run forword.I am new to socket,and i don't know how to solve it.could you please tell me how to do? Thanks. int
ddns3_sockio_read(int sock, char *buf, int len) {
 int ret;
 char err[100]; MYDEBUG( printf("run here (%s  %d\n) ... ", __FILE__,__LINE__)); //**********************************
 ret = recv(sock, buf, len, 0);
 MYDEBUG( printf("run here (%s  %d\n) ... ", __FILE__,__LINE__)); //**********************************
 if(ret < 0){
  //perror("read()");
  MYDEBUG( printf("run here (%s  %d\n) ... ", __FILE__,__LINE__)); //**********************************
  ddns3_sockio_error(err,100);
  MYDEBUG( printf("run here (%s  %d\n) ... ", __FILE__,__LINE__)); //**********************************
  fprintf(stderr, "recv(): %s\n", err);
 }
 MYDEBUG( printf("run here (%s  %d\n) ... ", __FILE__,__LINE__)); //**********************************
 
 return ret;
}
