Hi All, I'm getting following error when reading traces using babeltrace. I have enabled lttng using relayd and created live session.
I get this error till the time app is running. After app exits, babeltrace is able to read the traces. Is there any error in my config? or am i doing anything wrong here? $>babeltrace /var/tmp/lttng-traces/node/mysession-20141107-051543/ust/pid/logtrace-5797-20141107-061325/ [warning] Ill-shapen or missing "/* CTF x.y" header for text-only metadata.
