It seems to be sample-rate agnostic. I ran a few tests using GNURadio companion at 50M, 1M and 100K sample rates, they all had the same errors when stopping the flowgraph. For my application I need to run it at 50M.

After a few runs here I now have a new error too:
RuntimeError: RuntimeError: BIST failed!(code: 1)

The usrp flowgraph would not run until power cycling the usrp.

Side note: the errors do not appear if I kill the flowgraph using the stop button, as opposed to closing it cleanly.

Just to clarify, the "Bad CHDR" errors occur *during* streaming?

    I have a simple TX streamer that uses GNURadio in C++ which loads

    The problem I am having is that in my code, the log just spits out:
     "[ERROR] [STREAMER] Error parsing async message packet:
    ValueError: Bad CHDR or packet fragment"
     many times while streaming. Then when I stop streaming I get this:

    [ERROR] [UHD] Exception caught in safe-call.

    For me, this is not an isolated issue, no matter what program I
    run, be it my own, a uhd example, or a simple gnuradio-companion
    app I get these errors. And it seems to be causing my application
    to crash or not transmit properly.

    Is anyone else having this issue? Is there anything I can do to
    fix it? Is this ignorable?

    Setup: Windows 10 Home
    Intel Core i5
    X300
    Dual 10g ethernet using Intel X710 adapter

    Thanks for any assistance.

    Is this only at high sample rates, or is it sample-rate agnostic?
