Python套接字获取连接重置

我创建了一个线程套接字侦听器,它将新接受的连接存储在队列中。然后,套接字线程从队列中读取并响应。出于某种原因,当使用“ab”(apache benchmark)使用2或更多的并发性进行基准测试时,我总是在它能够完成基准测试之前重置连接(这是在本地进行的,因此没有外部连接问题)。

class server:    
_ip = ''
_port = 8888

def __init__(self, ip=None, port=None):
    if ip is not None:
        self._ip    = ip
    if port is not None:
        self._port  = port
    self.server_listener(self._ip, self._port)

def now(self):
    return time.ctime(time.time())

def http_responder(self, conn, addr):
    httpobj = http_builder()
    httpobj.header('HTTP/1.1 200 OK')
    httpobj.header('Content-Type: text/html; charset=UTF-8')
    httpobj.header('Connection: close')
    httpobj.body("Everything looks good")        
    data = httpobj.generate()

    sent = conn.sendall(data)


def http_thread(self, id):        
    self.log("THREAD %d: Starting Up..." % id)

    while True: 
        conn, addr = self.q.get()
        ip, port = addr
        self.log("THREAD %d: responding to request: %s:%s - %s" % (id, ip, port, self.now()))
        self.http_responder(conn, addr)                
        self.q.task_done()
        conn.close()

def server_listener(self, host, port):
    self.q = Queue.Queue(0)

    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock.bind( (host, port) )
    sock.listen(5)


    for i in xrange(4): #thread count
        thread.start_new(self.http_thread, (i+1, ))

    while True:
        self.q.put(sock.accept())

    sock.close()

server('', 9999)

编辑:我花了一段时间才弄明白,但问题出在 sock.listen(5)
