I would suspect that your setting of the time_spec with an uninitialized value could be a problem. rx_multi_samples sets up multi-channel RX with an initialized time_spec: https://github.com/EttusResearch/uhd/blob/UHD-3.15.LTS/host/examples/rx_multi_samples.cpp Can you compile and run that example on 3.15? -Sam Sam, Thanks for the suggestion. time_spec uninitialized takes the default of zero, right? If I run rx_multi_samples with --secs 0, I get an error “Error: Receiver error ERROR_CODE_LATE_COMMAND”, which we aren’t seeing in our usage (instead we just see it never return). If I run rx_multi_samples with another value (like --secs 0.1) it works fine. But the code I showed works 99.9% of the time. But when we run it for hours on end, it eventually locks up. I can try running rx_multi_samples with a very large --nsamps but that testing will take a while.
