Actually we have another setup with a different host and different B210 that shows a similar behavior. I had the feeling that when using "otw-format=sc12" for some of the configs we are running, the problem happens quicker. But it's just a feeling. Is there any known unsuitability or caveat when using sc12? In any case, I'll try to approach the issue a bit more systematic over the coming days/weeks and carefully swap cable/USRPs/hosts to see if we can identify a pattern. This may take a while though due to the current situation with lab access, etc. Anyway, if there is anything else that I could try, let me know.
