Exception: Failed to put IQ Samples into the Queue

1

Hello,

I’m having some trouble with heimdall and gnu radio, one of three scenarios happens:

  1. Throws Exception: Failed to put IQ Samples into the Queue immediately and repeatedly after running the flowchart.

  2. Throws Exception: Failed to put IQ Samples into the Queue after a random amount of time and never recovers, exceptions repeatedly until I terminate the file.

  3. It just works, but performance degrades over time, the DOA graph updates slower and slower.

I change nothing between reruns and the scenario changes. I’m guessing it has got something to do with queue overflowing? I tired turning down the sampling frequency but I’m not sure what that controls.

Any ideas of where I could look would be great!

Cheers,
Michael

What sort of system are you running on? Sounds like the computer isn’t able to keep up as the buffers get full.
