我有一个用 C++ 编写的非阻塞多线程节俭服务器和一个用 python 编写的节俭客户端。下面的代码片段简要展示了如何在 C++ 服务器和 python 客户端中完成节俭协议和绑定配置。

我的问题是，当 python 客户端通过 thrift 调用 C++ 服务器时，我在 C++ 服务器输出（即终端）中收到一条错误消息“ thrift non-blocking server overload condition ”，这已在第 3 和第 4 中指出下面的片段。我附上了通过 GDB 回溯命令检索到的堆栈，以供您参考。谁能告诉我我在这里缺少什么？您认为可能导致此错误的原因是什么。python 端或 C++ 端的节俭配置是否存在错误。请参考以下片段。我做了很多谷歌搜索，但到目前为止找不到线索。谢谢。

1) Python 客户端 - Thrift 配置

     try:
        self.transport = TSocket.TSocket( host , port)
        <----- NONBLOCKING --------->
        self.transport = TTransport.TFramedTransport(self.transport)    
        <----- NONBLOCKING --------->
        protocol = TBinaryProtocol.TBinaryProtocol(self.transport)


        # Instantiate the thrift client
        self.client = MyService.Client(protocol)
        # Connect to the thrift server
        self.transport.open()
        print 'Connection established via thrift...\n'

2) C++ 服务器 - Thrift 配置

    using boost::shared_ptr;
    printf("          *** Starting non-block THRIFT! ***\n");
    shared_ptr<MyServiceHandler> handler(new MyServiceHandler(this));
    shared_ptr<TProcessor> processor(new MyServiceProcessor(handler));
    shared_ptr<TProtocolFactory> protocolFactory(new TBinaryProtocolFactory());

    shared_ptr<ThreadManager>  threadManager=ThreadManager::newSimpleThreadManager(15);
    shared_ptr<PosixThreadFactory> threadFactory =
    shared_ptr<PosixThreadFactory>(new PosixThreadFactory());
    threadManager->threadFactory(threadFactory);
    threadManager->start();
    ats::TNonblockingServer server(processor,protocolFactory, port, threadManager);
    server.serve();

3) C++ 服务器中的错误输出

   !!!! ERROR BEGIN !!!! 
   Thrift: Tue Nov 15 17:59:49 2011 **thrift non-blocking server overload condition**
   !!!! ERROR IS END !!!!

4) GDB 回溯栈
