Should safe_asterisk be running with asterisk simultaneously?

I am inquirng of both processes safe_asterisk and asterisk be running simultaneously?

Thanks

Yes. It is a shell process that starts as root and changes the user to asterisk and then runs asterisk. IT also watches asterisk for a crash and restarts it if that happens so that the system can keep working.

More details can be found by reading up on how asterisk works.
