In-Reply-To: References: Message-ID: Hi Jenny, LTTng 2.5 has been unsupported for a while now. The oldest supported version is LTTng 2.7. You may want to update to the latest LTTng 2.8.x release and see if the problem persists. As for how to collect a back trace, if you have collected a core file, open it in GDB and use: (gdb) thread apply all bt full This should provide you with a complete back trace of all threads at the time of the crash.
