Error 57 after 20 queries using SocketNER

[dcalacci]

Consistently, if I have the stanford NER server running on my local machine, and I use pyner to make 20 consecutive queries - it doesn't matter how far apart in time they are - I receive the following error message and trace:

error: [Errno 57] Socket is not connected

I can use other ner client libraries to make consecutive requests, so I'm doubtful that the issue lies with the server code.

[dcalacci]

after some digging, it seems like this is an issue with py-amqplib:
https://code.google.com/p/py-amqplib/issues/detail?id=45

But, because of this bug, I can't successfully use the stanford ner server running on a socket using the pyner package on my machine, because I'm running OSX.

Alternatively, you can your local copy to call s.shutdown(...) between line 15 and 16 here. That way the exception is still handled and your socket will still close on OS X.

/usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ner-0.1-py2.7.egg/ner/utils.pyc in tcpip4_socket(host, port)
15 yield s
16 finally:
---> 17 s.shutdown(socket.SHUT_RDWR)
18 s.close()
