by RICHARD 49 views

Introduction

Hey guys! Today, we're diving deep into a rather pesky issue that some of you might have encountered while running Minecraft with the PCL CE launcher, specifically related to memory usage. This bug seems to surface during long play sessions and might be connected to specific mod configurations. Let's break down the problem, the steps to reproduce it, and what the error reports tell us. If you've been scratching your head over unexplained crashes and memory spikes, you're in the right place. We'll explore potential causes and solutions, ensuring you can get back to crafting and exploring without these interruptions. It's crucial to keep your gaming experience smooth and enjoyable, and understanding these technical details is a big step in achieving that.

Bug Report Overview

First off, I've already checked the Issues page on the PCL2-CE GitHub repository to make sure this hasn't been reported before. I'm also using the latest version of the launcher from the Fast Ring channel to ensure any already-fixed issues aren't the cause. The problem manifests as a probable memory issue caused by running Minecraft and PCL CE for an extended period. While it's not entirely certain, it might be related to specific configurations. Identifying the root cause of memory-related bugs in Minecraft, especially when using launchers like PCL CE, often requires a systematic approach. It involves monitoring resource usage, checking compatibility between mods, and analyzing crash reports. By following these steps, we can better understand what triggers these issues and find effective solutions.

These images show the state of the game and potential error messages that pop up when the memory issue occurs. Visual cues like these are super helpful in diagnosing the problem and figuring out what's going wrong under the hood. Observing how the game behaves just before the crash can provide valuable insights into the nature of the bug.

Steps to Reproduce

To reproduce this bug, follow these steps:

  1. Launch Minecraft 1.21.8 with Fabric 0.16.14. Make sure you have Fabric installed correctly and that you're using the specified version. Fabric is a mod loader, and getting the version right is crucial for compatibility. Using the wrong version can lead to unexpected issues and crashes. Starting with a clean installation of Fabric can help eliminate potential conflicts. This ensures that any problems you encounter are directly related to the mods being tested, rather than underlying issues with the mod loader itself.

    Note: Some mods are disabled, but still present in the mods folder. Loading these specific mods is crucial. Mod interactions can often lead to unexpected memory issues. By replicating the exact mod setup, we can isolate whether one of these mods or their combination is the culprit.

  3. Wait in the game until it crashes. Just let the game run and see if the crash occurs after some time. This step is all about observing the game over an extended period. Memory leaks and other long-term issues often don't manifest immediately. By allowing the game to run for a while, we increase the chances of triggering the bug and capturing the moment it happens.

Log Files and Attachments

Here are the relevant log files and attachments for further analysis:

Analyzing these log files is super important. They contain detailed information about what's happening in the game, including any errors, warnings, and exceptions that occur. By examining the logs, we can often pinpoint the exact cause of the crash and identify which mod or system component is misbehaving.

Analyzing the Error Report

Let's dive into what we can glean from the error report. Typically, these reports contain a stack trace, which shows the sequence of method calls that led to the crash. By examining the stack trace, we can often identify the specific function or mod that caused the issue. Memory-related errors might show up as OutOfMemoryError or similar exceptions. Additionally, the error report may contain information about the game's state, such as loaded chunks, entities, and other relevant data. All this information can help us understand the context in which the crash occurred.

Examining the Launch Log

The launch log provides insights into the startup process of the game. It shows which mods were loaded, any compatibility issues, and potential errors during initialization. By examining the launch log, we can verify that all the mods loaded correctly and that there were no initial warnings or errors that might have contributed to the memory issue. The launch log can also reveal if any mods are conflicting with each other or if there are missing dependencies. This information is crucial for troubleshooting mod-related problems.

Possible Causes and Solutions

Several factors could be contributing to this memory issue:

  1. Mod Interactions: Conflicts between mods can lead to memory leaks. Try disabling mods one by one to see if the issue resolves.
  2. Memory Allocation: Minecraft might not be allocated enough memory. Adjust the JVM arguments in the PCL CE launcher to increase the allocated RAM. For example, set -Xmx4G to allocate 4GB of RAM.
  3. Outdated Mods: Ensure all mods are up to date. Outdated mods can have bugs that cause memory issues.
  4. GPU Issues: The gpumemleakfix mod suggests there might be GPU-related memory leaks. Ensure your graphics drivers are up to date.
  5. Sodium and Iris: These mods can sometimes have compatibility issues. Try running the game without them to see if the problem persists.
