I am unsure, but I have 2 suggestions.

  1. You dont need the throttle block. The USRP sink throttles the stream.

  2. You should individually address the USRPs to avoid confusion over
    which “block” is which device:

Try making those fixes. If there error is still present, I recommend
sending a gdb traceback so we can know where the issue occurred.
