"lttng view"fails complaining about files not found, the trace directories are sometimes added to the path but the /root/lttng../../../channel0_* files are empty.=C2=A0I've followed the installation instructions from=C2=A0http://frederic-wou.net/lttng/and docs on=C2=A0https://lttng.org/docs/v2.10/=C2=A0These are the commands: "lttng enable -u a:b", "lttng start", <excercise-the-tracepoints>,"lttng stop" and "lttng view". lttng-consumerd is running. Running 'lttng-sessiond --vvv' returns DEBUG info and an error about server already runningWhat could be the reason for the failure, how can I debug it?</div><div dir="ltr" style="font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;">John<br></div><div><br></div></span><br></div></div></body></html>
