Consecutive call of parsim constantly increases memory usage (Ubuntu)

start_vals = [0.1, 0.08, 0.06, 0.04, 0.03, 0.02];
stop_vals = [0.04, 0.03, 0.02, 0.01, 0.0, -0.05];
batch_size = 50;
model = 'modelName';

cnt_exp = 0;
cnt_file = 0;
cnt_batch = 0;

for start_val = start_vals
    for stop_val = stop_vals
        cnt_exp = cnt_exp +1;
        
        MP = setParam(MP,start_val, stop_val)
        simulation_length = 12;
        cnt_batch = cnt_batch +1;
        sim_input(cnt_batch) = Simulink.SimulationInput(model);
        sim_input(cnt_batch) = sim_input(cnt_batch).setVariable('simulation_length',simulation_length);
        sim_input(cnt_batch) = sim_input(cnt_batch).setVariable('MP',MP);
        
        if cnt_batch < batch_size
            total_runs = cnt_file * batch_size + cnt_exp;
            if total_runs ~= sum_exp % last incomplete batch has to be processed
                continue;
            end
        end
        
        total_runs = cnt_file * batch_size + cnt_exp;
        try
            simOut = parsim(sim_input);
            for res = 1:length(simOut)
                % Process result
            end
            % Save results
            cnt_file = cnt_file +1;
            
            % Reset counters and arrays
            cnt_exp = 0;
            cnt_batch = 0;
            clear sim_input;
            
        catch error
            warning ("Something went wrong")
        end
    end
end

I'd greatly appreciate any help or hint on what is going wrong here!
