The sessiond take a short while to become ready. If you are running a script, I recommend using '-d' or '-b' to lttng-sessiond, instead of using "&".
Then, you need to wait for it to be ready, which can be done simply by a short sleep, or using signals (look at --sig-parent commandline argument). The reason you are seeing the error is that you are running lttng create before the sessiond is really ready.
