Twisted errors in Scrapy spider

Question

Hello,

When I run the spider from the Scrapy tutorial I get these error messages:

File "C:\Python26\lib\site-packages\twisted\internet\base.py", line 374, in fireEvent DeferredList(beforeResults).addCallback(self._continueFiring)  

File "C:\Python26\lib\site-packages\twisted\internet\defer.py", line 195, in addCallback callbackKeywords=kw)

File "C:\Python26\lib\site-packages\twisted\internet\defer.py", line 186, in addCallbacks self._runCallbacks()

File "C:\Python26\lib\site-packages\twisted\internet\defer.py", line 328, in_runCallbacks self.result = callback(self.result, *args, **kw)

--- <exception caught here> ---

File "C:\Python26\lib\site-packages\twisted\internet\base.py", line 387, in _continueFiring callable(*args, **kwargs)

File "C:\Python26\lib\site-packages\twisted\internet\posixbase.py", line 356, in listenTCP p.startListening()

File "C:\Python26\lib\site-packages\twisted\internet\tcp.py", line 858, in startListening raise CannotListenError, (self.interface, self.port, le) twisted.internet.error.CannotListenError: Couldn't listen on any:6023: [Errno 10048] 

Only one usage of each socket address (protocol/network address/port) is normally permitted.

Does anyone know what they are and how I can get rid of them?

Thanks

Perhaps you're running two Scrapy process simultaneously with telnet console enabled?.

If you want to run more than one Scrapy process at the same time, you must disable (or, at least, change the port) of web and telnet consoles.
