Thank you for your reply.
I'm used to QV where memory is not free up, and there are 'memory leaks'.
What I understand from you is that this is not the situation.
I also see that the RAM is increasing and decreasing rapidly so I guess that's why.
But I'm a bit concerned that the engine memory is too high, so I want to monitor the current apps and users, like in the QVS Statistics.
Is there a way to do so?
