MiniProfiler Timing memory leaks in applicazione ASP.NET C# MVC

Ciao,

ho memory leaks sul tipo string allocato dall'oggetto MiniProfiler.Timing. 
Su grosse moli di thread mi fa “scoppriare” la web app, scritta in c# ASP.NET MVB, .NET 6.0.

Eccovi una schermata parlante di dotMemory :

Anche forzando il GC la memoria non si dealloca.
L'utilizzo tipico che ne faccio è il seguente :

  using (MiniProfiler.Current.CustomTiming("http", $"POST {endpoint}"))
  {
      // Code       
  }

Come posso risolvere il problema?
Grazie,

Simone

    Quanto sono “grosse” queste moli di thread?

    Re: MiniProfiler Timing memory leaks in applicazione ASP.NET C# MVC

    Ciao colleghi, rispondo ad entrambi.

    1. Togliendo Miniprofiler i leak sulle stringhe spariscono. Sto valutando con la committente cosa fare.
    2. 10.000 thread con 500 thread in parallelo.

    L'applicazione di test fa così :

    using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Net.Http;
using System.Threading.Tasks;
namespace StressTestGaming
{
   class Program
   {
       static async Task Main(string[] args)
       {
           // Configuration options
           int numRequests = 10000; // Total number of requests to send
           int concurrencyLevel = 500; // Number of requests to send simultaneously
           string url = "https://localhost:44332/"; // URL to request
           // Create a list to hold the tasks for each request
           var tasks = new List<Task>();
           // Create an HTTP client to send the requests
           var httpClient = new HttpClient();
           // Create a stopwatch to measure the total time taken
           var stopwatch = Stopwatch.StartNew();
           // Start sending the requests in batches
           for (int i = 0; i < numRequests; i += concurrencyLevel)
           {
               Console.WriteLine($"Processing request number {i}");
               // Create a batch of requests to send simultaneously
               var batchTasks = new List<Task>();
               for (int j = 0; j < concurrencyLevel && i + j < numRequests; j++)
               {
                   batchTasks.Add(httpClient.GetAsync(url));
               }
               // Wait for all the requests in the batch to complete
               await Task.WhenAll(batchTasks);
               // Add the batch tasks to the overall task list
               tasks.AddRange(batchTasks);
           }
           // Wait for all the requests to complete
           await Task.WhenAll(tasks);
           // Stop the stopwatch and output the results
           stopwatch.Stop();
           Console.WriteLine($"Sent {numRequests} requests in {stopwatch.ElapsedMilliseconds} ms");
           Console.WriteLine($"Average response time: {stopwatch.ElapsedMilliseconds / (double)numRequests} ms");
           Console.ReadKey();
       }
   }
}

    Miniprofiler è avviato così :

     builder.Services.AddHttpContextAccessor()
       .AddMiniProfiler(options =>
       {
           options.RouteBasePath = "/profiler";
           options.TrackConnectionOpenClose = true;
           options.ColorScheme = StackExchange.Profiling.ColorScheme.Auto;
           options.EnableMvcFilterProfiling = true;
           options.EnableMvcViewProfiling = true;
           options.ResultsAuthorize = request =>
           {
               return request.HttpContext.User.IsInRole(Roles.Developer);
           };
       });

    Di una cosa sono certo : il fatto che l'applicazione sia scoppiata durante i test della conversione a .net 6.0 è un fatto puraente occasionale. Secondo me il problema c'era anche prima. Nel mentre ho risolto anche dei leaks legati all'utilizzo di redis.

    Attendo impressioni.
    Grazie,

    S.

    Entrambi chi? Ho risposto solo io al momento… :)

    10.000 thread con 500 thread in parallelo […]

    Innanzitutto, stai eseguendo Task e non Thread: il primo è una sorta di “virtualizzazione” del secondo, nata per astrarre il concetto di operazione asincrona, da cui poi il fatto che venga eseguito da un thread si può considerare un corollario.

    Detto questo, stai creando un discreto quantitativo di task simultaneamente, e se ogni task è correlato a una serie di operazioni che richiedono un certo quantitativo di memoria, ivi compresa quella per il task in quanto tale, mi sembra abbastanza naturale che il sistema arrivi a saturarsi.

    Non riesco comunque a farmi uno schema mentale dello scenario che stai testando e di come l'applicazione sia configurata nel sistema in cui esegue, quindi non vedendo dal vivo quello che avviene, mi risulta anche difficile fare ipotesi più particolari sui riscontri che ottieni… sorry.

    Alka ha risposto oltre a te. Hai qualche idea?

    L'eccezione che ricevo quando si “rompe tutto” è questa :

    Re: MiniProfiler Timing memory leaks in applicazione ASP.NET C# MVC

    Ciao,

    il tuo "Stress Test" invia una moltitudine di richieste GET asincrone all'url indicato dalla riga:

    string url = "https://localhost:44332/";

    Dopo circa 25 richieste (asincrone), il server non risponde più e la richiesta successiva si esaurisce per timeout (dopo 100 secondi). E si scaturisce un'eccezione. 

    Tutto assomiglia ad un attacco DOS (Denial Of Service), quindi… se il server si rifiuta di rispondere… mi sembra anche lecito.
