I'm using the Ettus provided UHD binaries (version

installed from
deb http://ppa.launchpad.net/ettusresearch/uhd/ubuntu bionic main
under Ubuntu 18.04.1 LTS with an USRP2 and WBX board.
I get near the end of the execution of both uhd_usrp_probe and
/usr/lib/uhd/examples/rx_samples_to_file the following error message:
[ERROR] [UHD] Exception caught in safe-call.

Any ideas what might cause this? (The same problem does not
occur with an N210 tested on the same PC.)
What happens if you ping the device aggressively (with longer packets,
and a higher cadence)??
