Hi Mingli,
sorry I missed these messages last week.
What version of babeltrace are you using when running the tests?
What distribution + version are you using?
There is a fix for hangs that may occur during the test, which is
included in stable-2.14 -
https://github.com/lttng/lttng-tools/commit/55d3f5e528059267f44fb24b179b992bf2b0cfa6
I've been working on replacing the test. I'd be curious to know if you
also see intermittent failures with the new version (e.g., is it a
detail in the test harness, or is the issue elsewhere).
