The synchronizer works fine, at least it does here. Try writing the output into a file, and then view it with gr_plot_char (or whatever you use). You will see a train of spikes at the distance of the length of the packets. The flow graph itself randomly stalls, though. I'm currently working on the reason, but it has to do with the large abuse of the scheduler. MB -- Karlsruhe Institute of Technology (KIT) Communications Engineering Lab (CEL) Dipl.-Ing.
