Custom search command executed multiple times with protocol v2

Hi, I thought my custom search command was working fine, until I added some logs.
The logs showed me that for a single call to the command, the code was run multiple (3-4) times.
My command is built using protocol version 2.

I'm aware of this question, but the answer looks like a hack.

Checkout the logs below. Does everything look fine to you? How can I fix it?

Example:

import logging

from splunklib.searchcommands import dispatch, EventingCommand, Configuration

logger = setup_logger(logging.DEBUG)
logger.info("start log")

@Configuration()
class OutputFTP(EventingCommand):

    def transform(self, records):
        logger.info('inside transform')
        for record in records:
            yield record


logger.info("before dispatch")
dispatch(OutputFTP, sys.argv, sys.stdin, sys.stdout, __name__)
logger.info("after dispatch")

Result logs:

It has been some time since you asked but do you have any idea why it was happening? I have the same issue, my script starts logger +2 times every time and sometimes even fails. I wonder if it is logger related issue or python interpreter issue.
