    Description

      As part of my university research I'm using Thrift v0.12.0 to communicate between Python server and Scala client. 

      The data my service is providing to client is lists of thrift objects/structs, those lists contain ~1M items. The issue bellow is produced if I'm sending full lists(more than ~60k items) of data, however if I decrease list items to ~60k everything works fine. 

      Traceback (most recent call last): 
      File "Server.py", line 40, in <module> 
      server.serve() 
      File "thrift/server/TNonblockingServer.py", line 370, in serve 
      self.handle() 
      File "thrift/server/TNonblockingServer.py", line 350, in handle 
      self.clients[writeable].write() 
      File "thrift/server/TNonblockingServer.py", line 88, in read 
      return func(self, *args, **kwargs) 
      File "thrift/server/TNonblockingServer.py", line 177, in write 
      self._wbuf = self.message[sent:] 
      AttributeError: 'Connection' object has no attribute 'message'
      

      This is my server configuration:

      ip = '127.0.0.1'
      port = '9000'
      handler = MyHandler()
      processor = MyService.Processor(handler)
      transport = TSocket.TServerSocket(host=ip, port=port)
      
      tfactory = TBinaryProtocol.TBinaryProtocolFactory()
      pfactory = TBinaryProtocol.TBinaryProtocolFactory()
      
      server = TNonblockingServer.TNonblockingServer(processor, transport, tfactory, pfactory)
      
      server.serve()
      

      Now my question is as follows, am I doing something wrong or could it be that it's an issue from Thrift? Any ideas how can I resolve this problem or what I could be doing wrong?

      Thanks in advance.
