What if autosizing produces unmet hours for the design days ?

I have set up an OS model with complete autosizing for 7 design days. I would like to achieve zero unmet hours for the design days. However, when increasing heating and cooling capacities manually, there seems to be little effect or even convergence problems during warming-up. Also the OS unmethours troubleshooting reporting measure failed, i.e. crashed.

What's your advice ?
