However, the initial state is wrong. It is left at the value 0, which indicates that a live beacon has indeed been received (which is untrue), which in turn causes a live beacon with ctf_stream_id of -1ULL to be sent to babeltrace, which does not expect it, and fails. This issue can be triggered with the following scenario: 1) create live session 2) setup UST per-uid buffers tracing 3) start tracing, without any active traced application 4) hook with babeltrace live client to view the trace 5) run a traced application Step 5) will cause the babeltrace live client to receive a stream_id of -1ULL, and error out.
