We have been researching stuck zombie processes in our libvirt lxc containers. What we found was: 1) Each zombie’s parent was pid 1. init which symlinks to systemd. 2) In some cases, the zombies were launched by systemd, in others the zombie was inherited. 3) While the child is in the zombie state, the parent process (systemd) /proc/1/status shows no pending signals. 4) Attaching gdb to
