Could you provide us the version used for babeltrace, lttng-tools and lttng-ust? > goes on, the delay will be bigger and bigger. A similar issues was observed a couple months ago, which implicated multiple delayed ack problems during communication between lttng-relayd and babeltrace. The following fixes were merged: [1] https://github.com/lttng/lttng-tools/commit/b6025e9476332b75eb8184345c3eb3e924780088 [2] https://github.com/efficios/babeltrace/commit/de417d04317ca3bc30f59685a9d19de670e4b11d [3] https://github.com/efficios/babeltrace/commit/4594dbd8f7c2af2446a3e310bee74ba4a2e9d648 In the event that you are already using an updated version of babeltrace and lttng-tools, it would be pertinent to provide us with a simple reproducer so we can assess the issue.
