If you play Minecraft a lot and continue to modify your system, you may have received this error/quote after a certain amount of time of Minecraft running:

“Failed to write core dump. Minidumps are not enabled by default on client versions of Windows.”

Some Windows 10 users may encounter the following error: “Failed to write core dump“. Minidumps are not enabled by default on client versions of Windows when they try to join or create a server. This error occurs in several Minecraft builds.

If you are running the game with a built-in Intel graphics card, the error is probably caused by a file in the dynamic link library (ig9icd64.dll). In this case, you should be able to solve the problem by using the Intel Update Wizard to install the latest drivers compatible with the embedded GPU.

On the other hand, if you are using a high-end Nvidia GPU, you may need to force Vsync and triple buffering directly to javaw.exe for the game to run stably.

If you are using an AMD card, try reinstalling the Catalyst or AMD software. A partially corrupted installation could cause this problem.

Create a Dump File

  1. Open the Minecraft startup device.
  2. Open Task Manager and go to Process for Windows 8/8.1 or Applications for 7.
  3. Right-click on Java(TM) Platform SE Binary or simply on your MC Launcher.
  4. find “Create Dump File” and click on it
  5. wait until the end and play Minecraft without screwing up

Update Java to the Latest Version

You have a problem in the native code. Updating Java will probably not help in this situation.

Updating Windows

This is only useful if the native code you are using is updated by Windows Updates.

Enable mini repositories via Advanced System Preferences — > Startup and Recovery — > Settings — > Select “small repository”.

This setting is for kernel mode crashes (blue screen), not application crashes (user mode). There is also a parameter for application crashes (a registry parameter called LocalDumps), but it does not work for Java because Java does its own exception handling.

To get crash dumps from Java 9 and higher, use the following command line switch :

-XX:+Create a kernel crash dump
On Java 8 and earlier, use the Windows specific command line

-XX:+Create a mini dumpster on the accident site.
This will give you more details about what happened at the time of the accident. It will still be an AccessViolation, but you will have the stack of calls and so on. – if you have the knowledge to debug it with WinDbg or similar.

Updating the Latest Intel Graphics Card Driver

If you are using an Intel integrated graphics card, you probably have a problem coming from the ig9icd64.dll file. This file is part of the OpenGL driver for the Intel graphics accelerator.

If this scenario applies to your current situation, you can solve the problem by updating the graphics driver set using the Intel Update Wizard.

Many affected users who have not been able to create Minecraft servers before have confirmed that this finally made the game stable.
