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.
