Optimisation Agents start producing slower results/stop while optimising an EA

 

Hi, 

I am writing because I encountered a problem regarding the optimisation. I've done already a few successful optimisation with this EA but after a while no matter in what mode or on what symbol I'm optimising 

the agents not working simultaneously and the optimisation starts slowing and almost stops. 

I have build 4350, i5-12400 with 16Gb RAM, Windows 10.

Anyone got any ideas?
