There are over 15 PA clients running when you are using gnome desktop

running  "pulseaudio -k  " to shutdown PA server , this kill all the PA
clients
restart PA  server by  "pulseaudio -vvvv" , only one or two PA clients (e.g.
consolekit, .. ) can connected back to PA server

This command "pulseaudio -k;pulseaudio -vvvv" cannot  provide a normal
environment to debug PA server since most of PA clients are killed
