Hello,that backtrace is from shutdown, if you don't have another core file, then the initial one was overwritten. You have to enable one core per process. In most of system it is:
echo "1" > /proc/sys/kernel/core_uses_pidYou have to reproduce the issue again and get the backtrace from all core files.
