Is there any workaround for this or any time by when this bug will be fixed

[avedor]

Where you create the DogStatsd class you can pass in the option disable_telemetry=True as a workaround

e.g.

DogStatsd(
        host=host, port=port, namespace=prefix, disable_telemetry=True
    )

This should be fixed in #902 which will be released soon.

[iamsfkhan]

@carlosroman Any idea when it is releasing ?
