Hello everybody,

In the following case study gr_file_source-> pll_clock_sync-> gr_complex_to_float -> custom_block(1 input, 2outputs) in gnuradio, by printing the counter of noutput_items of my custom block, I observe that it reaches up to a number of samples then it gets to zero and restarts again. Overall the number of output samples is the expected ones but why the counter over the noutput_items restarts at some time instants?

That's pretty typical behavior when running full-tilt (that it, when there's nothing controlling the rate like a radio, sound card, throttle, etc.).  I could give you some opinions on why I think it behaves this way, but they'd probably all be wrong. Most importantly, it's not a bug in your system, just how the scheduler adapts.
