Hi, I am randomly getting an error from my native C++ UHD application with USRP N320. I get an exception thrown:
EnvironmentError: IOError: socket closed If it happens, it happens on startup, before any samples have been received. This is usually, but not always followed by: [WARNING] [RFNOC::GRAPH::DETAIL] Cannot forward action rx_event from 0/Radio#0:OUTPUT_EDGE:0, no neighbour found! Any ideas? I tracked down this exception to the recv_udp_packets in uhd_common.hpp, but did not follow past that point. Currently I interpret this error as a hard failure and exit. Is that correct or is it actually benign? Thanks, Eugene Grayver, Ph.D. Principal Engineer 310-336-1274
