You can see the error message about csharp memory leak detection. Well, there are several ways to deal with this problem. We will do it shortly.

 

 

Anyone who has worked on a large business project knows that memory leaks are like rats in a big hotel. You may not notice if there are few of them, but you still need to be on the lookout if they overflow, burst into the kitchen and get dirty.

Finding and fixing memory leaks and learning how to prevent them is an important skill. I will list 8 best practices that I and experienced .NET developers have used who have recommended me for this article. These methods can help you identify when your application has a memory leak problem, find a specific memory leak, and fix it. Finally, I will include monitoring strategies and reporting memory leaks for the deployed program.

What Type Of Memory Leak? Shared Memory = Managed Memory Unmanaged Memory

Before trying to understand the nature of the leak, let’s try to understand how memory is allocated in .NET applications. .NET applications have two types of managed memory and unmanaged memory. Managed memory is controlled by the garbage collector, and unmanaged memory is outside the limits of the garbage collector.

Pe One thing we need to do to make sure a memory leak is happening is a managed leak or a raw leak. To determine if the leak has been repaired, two performance counters must be measured.

The first is the private application byte counter that we saw in the previous session.
The second counter we need to add is bytes in all heaps. Select .NET CLR Memory under the Performance object, select Bytes in All Heaps from the list of counters, and select the application that is losing memory.


Private bytes are all memory used by the application. The bytes of all heaps are memory used by managed code. Thus, the equation takes the form shown in the following figure.

Unmanaged memory bytes in all helpers = private bytes. Therefore, if we want to find unmanaged memory, we can always subtract the bytes of all heaps from the private bytes.

We will now make two statements:

  • If private bytes are incremented and the bytes in all heaps remain constant, it means an unhandled memory leak.

  • If the bytes of all heaps grow linearly, this indicates a controlled memory leak.

Here is a typical screen shot of a raw leak. You can see that the private bytes are incremented while the bytes in the heaps remain constant

Here is a typical screen shot of a managed leak. Bytes of all heaps are incremented.

How detect memory leak in .NET application?

Run the debug diagnostic tool, select Handle memory and leaks, and then click Next. Select the process in which you want to detect the memory leak. Finally, select “Activate Rule Now”. Now let the application run and the Debugdiag tool will run if there is any problem with the internal watchdog memory. December 13, 2018
