Dear list, I have a simple flowgraph with two branches, with different delays that are joined at the end. Imagine a topblock with A,B,C,D blocks. A is connected to B and C. B and C are connected to D. A and D are sink and source respectively. B and C produce packets (header and payload) from the input coming from A. D packets header and payload. The latency is different since B and C produce different sizes. A produces one sample per packet (it is a kind of signaling). All blocks are gr_block.
So, A produces a sample. It is delivered to B and C. Both produce header and payload using the sample produced by A. Finally, D joins together both inputs. I studied the delay between both branches and, since B is faster than C, the delay is increasing. After few minutes the flowgraph hangs and the difference of delaying is around 8000 packets. The flowgraph is in fact running. No stop is called but there are not any sample flowing. I use gnuradio master branch. Could you give me some hint for solving it?
