socket传输文件时传输一半就卡住了连接不到客户端了，麻烦各位大佬帮忙看一下

Question

int client(const char *serveraddr, const char *portnum)
{
struct sockaddr_in serv_addr;
char buf[MAXLINE];
int sock_id;
int read_len;
int send_len;
FILE *fp;
int i_ret;
int i = 0;

while(1)
{
    char filepath[100];
    sprintf(filepath, "images/img_%d.jpg", i);
    if ((fp = fopen((const char *)filepath,"r")) == NULL)
    {
        perror("Open file failed\n");
        printf("%s\n", filepath);
        exit(0);
    }   

/*<-----------------------------------------socket---------------------------------------------->/
if ((sock_id = socket(AF_INET,SOCK_STREAM,0)) < 0) {
perror("Create socket failed\n");
exit(0);
}
/<-----------------------------------------connect---------------------------------------------->*/
memset(&serv_addr, 0, sizeof(serv_addr));
serv_addr.sin_family = AF_INET;
serv_addr.sin_port = htons(atoi(portnum));
inet_pton(AF_INET, serveraddr, &serv_addr.sin_addr);

    i_ret = connect(sock_id, (struct sockaddr *)&serv_addr, sizeof(struct sockaddr));
    if (-1 == i_ret)
    {
        printf("Connect socket failed\n");
        return -1;
    }

/*<-------------------------------------client send part---------------------------------->*/
bzero(buf, MAXLINE);
while ((read_len = fread(buf, sizeof(char), MAXLINE, fp)) >0 )
{
send_len = send(sock_id, buf, read_len, 0);
if ( send_len < 0 )
{
perror("Send file failed\n");
exit(0);
}
bzero(buf, MAXLINE);
}

    printf("%s", filepath);
    printf(" SEND SUCCESSFUL\n");
    i ++;
    if (i >= 30)
        break;
}
fclose(fp);
close(sock_id);
return 0;

}
