Empty strategy optimization consume all available memory

[fx.practic]

Hello.
Each my optimization start to consume all available memory.
I removed code line by line from one of my strategy until this version:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Input;
using System.Windows.Media;
using System.Xml.Serialization;
using NinjaTrader.Cbi;
using NinjaTrader.Gui;
using NinjaTrader.Gui.Chart;
using NinjaTrader.Gui.SuperDom;
using NinjaTrader.Data;
using NinjaTrader.NinjaScript;
using NinjaTrader.Core.FloatingPoint;
using NinjaTrader.NinjaScript.Indicators;
using NinjaTrader.NinjaScript.DrawingTools;

namespace NinjaTrader.NinjaScript.Strategies.sIC
{
    public class sEmpty_MemoryLeaks : Strategy
    {
        [Range(0, double.MaxValue)]                 
        [NinjaScriptProperty] 
        [Display(GroupName = "01. Size",         Order = 2)] 
        public double    HeigthMinSizeK        { get; set; }
        
    }
} 

Here is video of how optimization of this strategy passed: 40 iterations on 2-month history consumed all available memory (about 10 Gb).

Hello,

Thank you for the post.

I just wanted to provide a quick note to let you know I am currently reviewing this case. Once I have more details from testing I will reply back here.

I look forward to being of further assistance

Hello,

I just wanted to reply back on this item.

During my testing, I had seen the memory increase but I had not seen the optimizer get stuck or otherwise affect the platform. Also, the memory was released sometime after my tests. I had run this past product management and it was determined to reduce the max kept results for your test to reduce the overall memory usage.

Are you seeing a situation with realistic settings that is also increasing memory in a non-standard way? I see using less max results does decrease the overall memory use. In your example there is a maximum of 100 results, was there a reason you are trying to retain 10000?

Please let me know if I may be of further assistance.

When I run optimization, I always want to keep all results of all iteration.
So, I put excess number of results to not loose anyone.
