Logging failing after a while

edit

Hi,

I have a program that if I run multiple times inside the cloud sage worksheet, after a while (3-4 runs) gets a strange KeyboardInterrupt error.

Do you know what it is

Here is the code to reproduce the problem:

import logging
import logging.config
import logging.handlers

import sys

# Set logging facilities
#
logger = logging.getLogger()
logger.setLevel(logging.DEBUG)
loggingStreamHandler = logging.StreamHandler(sys.stdout)
loggingStreamHandler.setFormatter(logging.Formatter('%(asctime)s - %(levelname)s --- %(message)s'))
logger.addHandler(loggingStreamHandler)

for i in range(100):
    logger.info ("Ciaooooooo: %s", 1000)

logger.info ("End: %s", 1000)

2016-06-09 14:06:18,765 - INFO --- Ciaooooooo: 1000
2016-06-09 14:06:18,766 - INFO --- Ciaooooooo: 1000
2016-06-09 14:06:18,767 - INFO --- Ciaooooooo: 1000
2016-06-09 14:06:18,767 - INFO --- Ciaooooooo: 1000
