+From d284752e616dfc4c9288be3bb21c04ea78cdd967 Mon Sep 17 00:00:00 2001
+From: Francis Deslauriers <francis.deslauriers@efficios.com>
+Date: Wed, 8 Sep 2021 10:16:23 -0400
+Subject: [PATCH 2/2] Fix: Tests: race condition in test_ns_contexts_change
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Issue
+=====
+The test script doesn't wait for the test application to complete before
+stopping the tracing session. The race is that depending on the
+scheduling the application is not always done generating events when the
+session is stopped.
+
+Fix
+===
+Make the test script wait for the termination of the test app before
+stopping the session.
