I have noticed that on my system /usr/pluto/bin/Start_NewMD_interactor.sh takes a lot of CPU.
It starts "/usr/pluto/bin/interactor-server" ( whatever it does) in a loop. And it seems that if it already for some reason is running, then interactor-server says that the port is already used and exits. That creates a lot of starts and take quite some CPU.
Something like this might be better :
while :; do
killall /usr/pluto/bin/interactor-server 2>/dev/null
