duplicated log messages

[samlesu]

We updated Thespian from 3.4.0 to 3.6.0 and we notice that all the logs emitted by an Actor are duplicated using the Python default formatting (and not the logs emitted by the main thread).

So the output looks like this for instance:

2017-01-12 11:42:35,787 - sandman.actors.actor:41[29] - INFO - Creating actor Client
INFO:sandman.actors.actor:Creating actor Client

We are using the multiprocTCPBase system base. I'm manually configuring my local loggers and setting up the thespian loggers using the configuration provided in the documentation.

Are we doing something wrong?

Do you have propagate = True and multiple loggers potentially handling the message? If you could share your logging configuration I could see if this is something I could reproduce.

Thanks for your quick reply, adding propagate = True on my package logger solve it.
