Python多进程处理并发TCP请求导致客户端卡死的原因是什么？

import os
import socket
import sys
import time
import threading
from loguru import logger
from concurrent.futures import ThreadPoolExecutor
from concurrent.futures._base import Future
import multiprocessing

default_encoding: str = 'utf-8'

# ... (init_serversocket function remains unchanged) ...

def send_response(clientsocket: socket.socket, addr: tuple, response_body: bytes) -> int:
    send_len: int = clientsocket.send(response_body)
    clientsocket.close()
    return send_len

def start_request(clientsocket_fd: int, addr: tuple) -> int:
    clientsocket = socket.fromfd(clientsocket_fd, socket.AF_INET, socket.SOCK_STREAM)
    os.close(clientsocket_fd)  # Close the FD after duplication

    try:
        pid = os.getpid()
        logger.debug(f'pid: {pid}, get message from {addr}')
        request_body: bytes = clientsocket.recv(2048)
        request_text: str = request_body.decode(encoding=default_encoding)
        response_text: str = f'server get message: {request_text}'
        response_body: bytes = response_text.encode(default_encoding)
        send_len = send_response(clientsocket, addr, response_body)
        logger.debug(f'发送了响应')
        return send_len
    except Exception as error:
        logger.exception(error)
    finally:
        clientsocket.close() # Ensure closure even if exceptions occur


def worker_process(clientsocket_fd, addr):
    start_request(clientsocket_fd, addr)

# ... (rest of the code remains largely unchanged) ...
