Core dump error when trying to run asp netcore app under ubuntu 16 04


ASP.NET is a popular programming language used for building web applications. It provides a framework for developing dynamic , web services, and web APIs. However, like any other programming language, ASP.NET developers may encounter and issues while working on their . One common error that developers may face is the “Core dump error” when to run an ASP.NET Core app under Ubuntu 16.04.

Understanding the Core Dump Error

A core dump is a file that contains the memory image of a running program at the time it crashed. It can be useful for debugging purposes as it provides information about the state of the program when the crash occurred. However, encountering a core dump error indicates that the ASP.NET Core app has crashed and generated a core dump file.

Possible Causes of the Core Dump Error

There can be several reasons behind the core dump error when running an ASP.NET Core app under Ubuntu 16.04. Some of the common causes :

  • Memory-related issues
  • Incompatible dependencies
  • Incorrect configuration settings
  • Hardware or system-related problems

Solving the Core Dump Error

To solve the core dump error, you can follow these steps:

Step 1: the Core Dump File

The first step is to analyze the core dump file generated by the ASP.NET Core app. You can use tools like GDB (GNU Debugger) to examine the core dump file and identify the cause of the crash. GDB provides various commands to analyze the memory image and stack trace, helping you pinpoint the issue.


Step 2: Check Memory

Memory-related issues can often lead to core dump errors. Make sure that your ASP.NET Core app is not consuming excessive memory or encountering memory leaks. You can use tools like Valgrind to analyze memory usage and detect any memory-related problems.

Step 3: Verify Dependencies

Ensure that all the dependencies used by your ASP.NET Core app are compatible with the Ubuntu 16.04 . Incompatible dependencies can cause crashes and core dump errors. Check the versions of the libraries and frameworks you are using and update them if necessary.

Step 4: Review Configuration Settings

Incorrect configuration settings can also lead to core dump errors. Review the configuration files of your ASP.NET Core app and ensure that all the settings are correct. Pay special attention to any environment-specific configurations that may be the issue.

Step 5: Check Hardware and System

In some cases, the core dump error may be caused by hardware or system-related problems. Ensure that your Ubuntu 16.04 system is up to date with the latest patches and . Check for any hardware issues that may be affecting the stability of your ASP.NET Core app.


The core dump error when trying to run an ASP.NET Core app under Ubuntu 16.04 can be frustrating, but by following the steps outlined above, you can troubleshoot and resolve the issue. Remember to analyze the core dump file, check memory usage, verify dependencies, review configuration settings, and ensure the stability of your hardware and system. By addressing these potential causes, you can overcome the core dump error and continue developing your ASP.NET Core app smoothly.
