Hi Johan, Thanx for your answer.
Setting MaxIdleInstances to 3 did force the resident instances to be used instead of the dynamic ones. As we will soon pay for active instances, I would haved like to have the 3 resident ones being used instead of extra dynamic ones being started. Thanx again for your help.
