[CentOS] running init disconnects ssh session

Noticing a new behavior lately.  Logged in via sshd and ssh keys as root 
to a remote system.  When changing runlevels between multi-user or 
graphical the ssh session is disconnected.  It's not a big deal but 
annoying if I have other tasks to do on that particular system.  I've 
tried logging in as normal user, su to root and it still disconnects the 
ssh session upon either an "init 3" or "systemctl isolate 
multi-user.target" command.
