Menu Future of Memory Clean 03 January 2019. TLDR; To get the latest version of Memory Clean 2 for free, please click here. After many years of maintaining support for Memory Clean 1 and Memory Clean 2 via the Mac App Store, we will be switching to direct distribution of critical updates via our website. Know that physical memory is the amount of storage on your computer. Physical memory is like a USB stick or hard drive - it holds music, photos, files, etc. This is different from Random Access Memory, or RAM, which partially controls PC function. There are two kinds of memory, physical and random access (RAM). To make sure the memory is being used in the best way it can and avoid memory leaks and such using up all the memory. Lots of people feel the memory is a resource and should be used as much as possible. However, eliminating, the left over trash is generally a good idea. So how does CleanMem work? CleanMem Works buy calling a Windows API.
A pop-up will appear on your screen, asking how you'd like to go about checking the memory. The first option will restart your machine and check the memory right now, and the second option. 2.Find Explorer and click Restart. By doing this operation, the Windows will potentially free up some memory RAM. Install A RAM Cleaner Software/Tool. Under most circumstances, it's effortless to clean the memory and free up RAM with professional RAM cleaner software.
The review for Memory Cleaner has not been completed yet, but it was tested by an editor here on a PC and a list of features has been compiled; see below.
Improves the speed on the available memory on your systemTech-savvy folk are divided over how useful memory cleaning tools can be because Windows (Vista upwards at least) manage memory reasonably well. Most memory cleaning tools are not very useful because many of them use ill-advised techniques that are only relevant to older versions of Windows (pre-Vista).
MemoryCleaner is considerably better because it uses functions built into Windows to judiciously free memory - with no performance impact whatsoever. You can now access Memory Cleaner functions from the tray icon without having to open up the main window. The cleaning prodecures are both silent and the only alert you will see is the amount of RAM recovered briefly displayed in the window.
If you find your RAM usage exceeding 60% regularly, then MemoryCleaner is an absolute must have.
Features and highlights
- Trims processes working set
- Clears system cache
- Monitors RAM usage and reports minimum, maximum and average (true average, not (min max)/2)
- Reports Pagefile and virtual memory usage

A memory leak may happen when your app references objects that it no longer needs to perform the desired task. Referencing said objects makes the garbage collector to be unable to reclaim the memory used, often resulting in performance degradation and potentially end up throwing a OutOfMemoryException.
This tutorial demonstrates the tools to analyze a memory leak in a .NET Core app using the .NET diagnostics CLI tools. If you are on Windows, you may be able to use Visual Studio's Memory Diagnostic tools to debug the memory leak.
This tutorial uses a sample app, which is designed to intentionally leak memory. The sample is provided as an exercise. You can analyze an app that is unintentionally leaking memory too.
In this tutorial, you will:
- Examine managed memory usage with dotnet-counters.
- Generate a dump file.
- Analyze the memory usage using the dump file.
Prerequisites
The tutorial uses:
- .NET Core 3.1 SDK or a later version.
- dotnet-counters to check managed memory usage.
- dotnet-dump to collect and analyze a dump file.
- A sample debug target app to diagnose.
The tutorial assumes the sample and tools are installed and ready to use.
Examine managed memory usage
Before you start collecting diagnostics data to help us root cause this scenario, you need to make sure you're actually seeing a memory leak (memory growth). You can use the dotnet-counters tool to confirm that.
Open a console window and navigate to the directory where you downloaded and unzipped the sample debug target. Run the target:
From a separate console, find the process ID:
The output should be similar to:
Now, check managed memory usage with the dotnet-counters tool. The
--refresh-interval
specifies the number of seconds between refreshes:The live output should be similar to:
Focusing on this line:
You can see that the managed heap memory is 4 MB right after startup.
Now, hit the URL
https://localhost:5001/api/diagscenario/memleak/20000
.Observe that the memory usage has grown to 30 MB.
By watching the memory usage, you can safely say that memory is growing or leaking. The next step is to collect the right data for memory analysis.
Generate memory dump
When analyzing possible memory leaks, you need access to the app's memory heap. Then you can analyze the memory contents. Looking at relationships between objects, you create theories on why memory isn't being freed. A common diagnostics data source is a memory dump on Windows or the equivalent core dump on Linux. To generate a dump of a .NET Core application, you can use the dotnet-dump tool.
Using the sample debug target previously started, run the following command to generate a Linux core dump:
The result is a core dump located in the same folder.
Restart the failed process
Once the dump is collected, you should have sufficient information to diagnose the failed process. If the failed process is running on a production server, now it's the ideal time for short-term remediation by restarting the process.
In this tutorial, you're now done with the Sample debug target and you can close it. Navigate to the terminal that started the server, and press Ctrl+C.
Analyze the core dump
Now that you have a core dump generated, use the dotnet-dump tool to analyze the dump:
Where
core_20190430_185145
is the name of the core dump you want to analyze.Note
If you see an error complaining that libdl.so cannot be found, you may have to install the libc6-dev package. For more information, see Prerequisites for .NET Core on Linux.

You'll be presented with a prompt where you can enter SOS commands. Commonly, the first thing you want to look at is the overall state of the managed heap:
Here you can see that most objects are either
String
or Customer
objects.You can use the
dumpheap
command again with the method table (MT) to get a list of all the String
instances:You can now use the
gcroot
command on a System.String
instance to see how and why the object is rooted. Be patient because this command takes several minutes with a 30-MB heap:You can see that the
String
is directly held by the Customer
object and indirectly held by a CustomerCache
object.You can continue dumping out objects to see that most
String
objects follow a similar pattern. At this point, the investigation provided sufficient information to identify the root cause in your code.This general procedure allows you to identify the source of major memory leaks.
Clean up resources

In this tutorial, you started a sample web server. This server should have been shut down as explained in the Restart the failed process section.
You can also delete the dump file that was created.
