I had to restart services earlier today.
All services (app beacon bg & nsa) stopped and looked to have restarted successfully. But when I do a 'service status all' I see that app and nsa have stopped again.
I tried removing all services and re-adding. But I get errors when I try to deploy all.
So now, when I try service status all I see that beacon & bg are started but nsa and app are not.
I had a look in the admin.log file but cannot see anything there which might explain what is happening.
