Hi Martin I am still trying to investigate this issue, recreating it is difficult as it can take long time.
However, on a system that crashed I observed a thread “uhd_ctrl_ep0001” specifically its CPU utilisation (I have isolated this to use a single CPU and not share it). Normally it is below \~20%, (when first starting our application is is < 10%) once there is a failure (as per the discussion here), this thread has a higher utilisation (not 100%), around 30-40%. When kill our process, and restart, the CPU utilisation is still high from the start. The only way to recover is to power off the USRP-2974 and on again. Kind regards Marino
