[Discuss-gnuradio] Flowgraph with BER Block freezing

[adrian . perez . portero]

I have been trying to incorporate BER measures in a more complex  
flowgraph that includes OFDM.
I created a basic example to understand it better, but to my surprise  
when I run it, it stops after 2 seconds approximately. The interface  
is working, but the FFT Sink and BER Number Sink are stopped. If I  
disable the BER block and the Virtual Source and Number Sink, and  
instead enable the Tag Debug, the flowgraph keeps running indefinitely.
I attached bertest.grc to this message.
