Hi Aaron, You will have to provide the verbose logs of the session daemon. So, quite simple, start in an other console the session daemon with your user like so:
$ lttng-sessiond -vvv --verbose-consumer > /tmp/sessiond.log And do the "lttng" commands again. It's going to be quite easier to identify the problem. A Fatal error of the session daemon, I suspect something is not right with the installation or you are missing memory which I doubt :). Thanks!
