Side note, the stable 2.10 branch latest release is 2.10.6. I encourage you to upgrade regardless of this problem. > Once session is created and streaming starts on node, > suddenly babel-trace exit with code 0(Zero) and restart. This happens in a AFAIK we do not provide any automatic way to start babeltrace on session creation. Can you explain how babeltrace is launched? Are you using "lttng view"? Launching it manually on another host? Are you using a wrapper for babeltrace that tries to connect to a session in a loop? > silent loop until we kill the lttng process.

The first step, and one you should have done before sending this email, is to read [1] and gather as much information as possible, at least logs for: babeltrace, lttng-session, lttng-relayd . Then open a bug on [2].
