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.
Regards,
Jérémie
