Python HTTP服务器：崩溃

Question

我有python http服务器。此http服务器侦听传入的post请求（100-150个同时连接）。 我的python服务器在工作一天后崩溃并关闭。在

这是我的代码：

import http.server
import socketserver
import queue
import socket
import gzip
from urllib.parse import parse_qs
import json
import time
import _thread as thread
import threading
import globals
from logs import LOG
import conf
from os import getcwd
from DBConnection import DB

mutex = None
MAX_THREADS = 25

如何解决这个问题？还有其他方法可以做http服务器吗？在
