I have a simple TX streamer that uses GNURadio in C++ which loads data
from a file into memory followed by a separate flowgraph of vector
source to usrp sink that repeats until closed.
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

Thanks for any assistance.

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