It is still unclear, however, where and how TLR7-mediated interactions affect the development of autoreactive B cells. You can also delete the dump file that was created.Toll-like receptor (TLR), a ligand for single-stranded RNA, has been implicated in the development of pathogenic anti-RNA autoantibodies both in systemic lupus erythematous (SLE) patients and in murine models of lupus. This server should have been shut down as explained in the Restart the failed process section. In this tutorial, you started a sample web server. This general procedure allows you to identify the source of major memory leaks. At this point, the investigation provided sufficient information to identify the root cause in your code. You can continue dumping out objects to see that most String objects follow a similar pattern. You can see that the String is directly held by the Customer object and indirectly held by a CustomerCache object. Be patient because this command takes several minutes with a 30-MB heap: > gcroot -all 00007f6ad09421f8Ġ0007F6795BB58A0 00007F6C1D7D0745 .PollForValues() You can now use the gcroot command on a System.String instance to see how and why the object is rooted. You can use the dumpheap command again with the method table (MT) to get a list of all the String instances: > dumpheap -mt 00007faddaa50f90 Here you can see that most objects are either String or Customer objects. You'll be presented with a prompt where you can enter SOS commands. For more information, see Prerequisites for.

If you see an error complaining that libdl.so cannot be found, you may have to install the libc6-dev package. Where core_20190430_185145 is the name of the core dump you want to analyze. Now that you have a core dump generated, use the dotnet-dump tool to analyze the dump: dotnet-dump analyze core_20190430_185145 Navigate to the terminal that started the server, and press Ctrl+C. In this tutorial, you're now done with the Sample debug target and you can close it. If the failed process is running on a production server, now it's the ideal time for short-term remediation by restarting the process. Once the dump is collected, you should have sufficient information to diagnose the failed process. The result is a core dump located in the same folder.

Using the sample debug target previously started, run the following command to generate a Linux core dump: dotnet-dump collect -p 4807 NET Core application, you can use the dotnet-dump tool.

A common diagnostics data source is a memory dump on Windows or the equivalent core dump on Linux. Looking at relationships between objects, you create theories on why memory isn't being freed. Then you can analyze the memory contents. When analyzing possible memory leaks, you need access to the app's memory heap. The next step is to collect the right data for memory analysis. GC Heap Size (MB) 30īy watching the memory usage, you can safely say that memory is growing or leaking. Now, hit the URL Observe that the memory usage has grown to 30 MB. You can see that the managed heap memory is 4 MB right after startup. The live output should be similar to: Press p to pause, r to resume, q to quit.įocusing on this line: GC Heap Size (MB) 4 The -refresh-interval specifies the number of seconds between refreshes: dotnet-counters monitor -refresh-interval 1 -p 4807 Now, check managed memory usage with the dotnet-counters tool.

The output should be similar to: 4807 DiagnosticScena /home/user/git/samples/core/diagnostics/DiagnosticScenarios/bin/Debug/netcoreapp3.0/DiagnosticScenarios Run the target: dotnet runįrom a separate console, find the process ID: dotnet-counters ps Open a console window and navigate to the directory where you downloaded and unzipped the sample debug target.

You can use the dotnet-counters tool to confirm that. Examine managed memory usageīefore 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). The tutorial assumes the sample and tools are installed and ready to use. dotnet-dump to collect and analyze a dump file.dotnet-counters to check managed memory usage.Analyze the memory usage using the dump file.Examine managed memory usage with dotnet-counters.
