10+ Pro Methods To Solve “Failed To Write Core Dump” Error In Minecraft

Failed To Write Core Dump

We all love to play Minecraft, as it is one of the most thrilling sandboxes ever produced. But it does irritate us whenever the system has failed to write core dump repeatedly, isn’t it? However, the issue can be way more deep-rooted than you can possibly imagine.

Using an obsolete version of Windows, Java, or even GPU driver can trigger the core dump error in Minecraft. Besides, a disabled small memory dump or an incompatible JDK version can cause this issue. It can also trigger if you have disabled the VSync and triple buffering in Nvidia GPU.

However, a few general methods and some advanced tweaks can effectively rectify this error in no time and assure smoother gameplay. But before we delve deep, let’s understand the root causes of this error in detail.

What Are The Primary Causes Of The “Failed To Write Core Dump” Error?

If your system has constantly failed to write core dump, especially while playing Minecraft, there can be several reasons behind it. But in a broader spectrum, this error can typically trigger for seven main reasons.

  1. You are using an outdated network or GPU driver which are incompatible with Minecraft.
  2. The version of your Windows OS is obsolete and needs an update.
  3. You are using an obsolete version of Java that is not supported by the latest Minecraft version.
  4. Minidumps or automatic dumps are disabled in your system.
  5. A third-part antivirus or firewall is interfering with Minecraft in the background.
  6. If you are using an AMD graphics card, you may have a faulty “Catalyst Utility” installed.
  7. If you use an Nvidia graphics card, you may have disabled the VSync and triple buffering options.

Even while the Mojang developers release updates in a timely manner to fix the bugs, many gamers still reported getting graphical errors, such as a broken bow or a jittery screen. If you face the same issue, you can follow our detailed guide to repair bows in Minecraft on the Windows system.
