本人开启100个线程工作，重写了run方法，结束后循环再次开启100个线程，一直这样循环，在开启到一定数量的时候（本机所能开启的最大线程数）提示报错：can't start new thread
看了一下，原来开启的线程虽然工作结束了，但是所占的资源没释放，造成这个原因，网上查找无果，求大佬指导，上代码：
import threading , time from queue import Queue class BdSpider(threading.Thread): def __init__(self, waiting): super(BdSpider, self).__init__() self.waiting = waiting self.flag = True def run(self): while self.flag: ipone = self.waiting.get() self.waiting.task_done() def ssss(self): self.flag = False def ipAction(): for i in range(10): aaa = [] wait_list = Queue() thread_num = 20 for keyip in range(2000): if keyip: wait_list.put(keyip)#往Queue添加 for ii in range(100): print(ii + i*100) thread = BdSpider(wait_list) thread.setDaemon(True)#设置守护进程 thread.start() aaa.append(thread) wait_list.join() for ii in aaa: ii.ssss() print("-------------------------------") print(threading.active_count())#打印当前线程数 ipAction() print("main ------") print(threading.active_count())
打印线程数也是一直增加到极限
报错：
Traceback (most recent call last): File "xiancheng.py", line 36, in <module> ipAction() File "xiancheng.py", line 29, in ipAction thread.start() File "C:\Users\hujjjj\AppData\Local\Programs\Python\Python36-32\lib\threading.py", line 846, in start _start_new_thread(self._bootstrap, ()) RuntimeError: can't start new thread
