Alone user data dir with several browser instance

Is it imposible to use alone user data dir with several browser instance?

I should verify feature by automation testing(Robor Framework). I need to open several browser instances and point the same user data dir and used profile. But my tryings to open the second instance with the same user data dir finish with message:

INFO Creating an instance of the Chrome WebDriver.
FAIL InvalidArgumentException: Message: invalid argument: user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir

Thanks in advance!
