twisted.internet.error.ConnectionLost

[phob0s]

Hello,

I am beginner in python coding.

I installed python JasminSMS and everything works except that the script to record the messages stops at this:

Connected to broker.
Unhandled Error
Traceback (most recent call last):
Failure: txamqp.client.Closed: [Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionLost'>: Connection to the other side was lost in a non-clean fashion.
]

I do have no idea what it is, python twisted is well installed.

Here is the code :

Purpose:
- Integrates PySQLPool lib to handle MySQL
- Visit https://pythonhosted.org/PySQLPool/tutorial.html
 
Requirements:
- Pip
- libmysqlclient-dev
- PySQLPool library
 
To prepare in Debian:
  apt-get install libmysqlclient-dev
  pip install PySQLPool

TO-DO:
- Wrap the MySQL execs in a try/catch to track any exeptions

    This example will connect to RabbitMQ broker and consume from two route keys:

      - submit.sm.resp.*: More relevant than SubmitSM because it contains the sending status
 
    Note:
      - Messages consumed from submit.sm.resp.* are not verbose enough, they contain only message-id and status
      - Message content can be obtained from submit.sm.*, the message-id will be the same when consuming from submit.sm.resp.*,
        it is used for mapping.
      - Billing information is contained in messages consumed from submit.sm.*
