Of particular note from that article:
To remove zombies from a system, the SIGCHLD signal can be sent to the
parent manually, using the kill command. If the parent process still
refuses to reap the zombie, the next step would be to remove the parent
process. When a process loses its parent, init becomes its new parent.
Init periodically executes the wait system call to reap any zombies with
init as parent.
