[Discuss-gnuradio] Error on GNUradio

Hello,

We will be running a basic flow graph to test our antenna with the LimeSDR.

The flowgraph is basically an osmocom source--> WX GUI waterfall sink.

It will run perfectly fine for some operations and then every once in a while we will run it and get this error. It then works fine after we hit the reset button on the LimeSDR.

We will get this error.

If anyone knows what is going on, that would be great.
