[Twisted-Python] file descriptor cannot be a negative integer (-1)

[ruslan usifov]

Sorry fo my question. I'm new in twisted ad may misunderstand some
things:-), and my questions may look like trivial

I have follow stack trace:

cant connect to fcgi socket: [Failure instance: Traceback: <type
'exceptions.ValueError'>: file descriptor can not be a negative integer (-1)
/usr/local/lib/python2.6/site-packages/twisted/internet/base.py:796:runUntilCurrent

My connectionMade function looks like this:

    def connectionMade(protocol):
      protocol._setPeer(self);
      self._setPeer(protocol);

      for chunk in self._chunks:
        protocol.transport.write(chunk);

      self._chunks = [];
      self.transport.resumeProducing();



All code that i use look like this:
  def proxy(self):
    def connectionMade(protocol):
      protocol._setPeer(self);
      self._setPeer(protocol);

      for chunk in self._chunks:
        protocol.transport.write(chunk);

      self._chunks = [];
      self.transport.resumeProducing();

    def cantConnect(fail):
      log.err("cant connect to fcgi socket: %s" % (fail.getErrorMessage()));
      self.transport.loseConnection();

    #устанавливаем соединение с реальным обработчиком (в нашем случае это
php)
    self.transport.pauseProducing();
    l_client = protocol.ClientCreator(reactor, Proxy);

l_client.connectUNIX(self.factory.proxysock).addCallback(connectionMade).addErrback(cantConnect);


Its a simply fastcgi proxy, which reads all request(analize it, do some
pending things and then proxy request to real worker)
Thank for your help.

PS: i use kqreactor.py from this branch
