The Garbage Collector is the JVM's housekeeper. It finds and removes objects that are no longer in use. Different GC algorithms have different performance characteristics.
If the crash happens during gameplay or hosting:
: Available in newer Java versions; optimizes ZGC to treat young (newly created) and old game objects differently, cutting CPU usage.
Based on in-depth community guides, here is a powerful set of JVM arguments you can combine for advanced tuning: zulu platform x64 architecture project zomboid
java -server -Xms6G -Xmx8G -XX:+UseG1GC -XX:+UseStringDeduplication -jar ProjectZomboidServer.jar
-XX:+UseG1GC : Forces the JVM to use the high-efficiency Garbage-First Garbage Collector.
Summary Zulu Platform x64 Architecture for Project Zomboid is a tailored runtime distribution of OpenJDK (Zulu) built specifically to support the x64 architecture needs of the Project Zomboid community. It focuses on compatibility, stability, and performance for a modern Java-based game that demands reliable memory management, efficient I/O, and predictable threading behavior on 64-bit systems.

Here is a proper post formatted for a support forum (like Reddit, Steam Discussions, or the Indie Stone Forums) or as a technical documentation reference.
In conclusion, the combination of Zulu Platform and x64 architecture offers a powerful solution for Project Zomboid, enabling the game to scale efficiently, utilize resources effectively, and provide a secure and immersive experience for players. By leveraging Zulu Platform's features and the benefits of x64 architecture, Project Zomboid can continue to grow and thrive, delivering a world-class gaming experience to its dedicated community.
Here is a comprehensive guide to understanding, installing, and configuring the Zulu Platform x64 OpenJDK to maximize your Project Zomboid performance. Why Project Zomboid Needs a Custom JVM If the crash happens during gameplay or hosting:
Open Task Manager (Ctrl+Shift+Esc), find Zulu Platform x64 Architecture , and select End Task .
The specification means it is explicitly compiled for 64-bit operating systems and processors. Unlike 32-bit systems, which are strictly limited to utilizing 4GB of RAM, a 64-bit architecture unlocks virtually unlimited memory access. For a heavily modded or long-term Project Zomboid session, this architectural capability is mandatory. Why Project Zomboid Struggles with Default Java
Zulu may appear to "take" all available memory. However, the JVM is designed to request memory from the OS and release it reluctantly, preferring to keep allocated pages for performance. What matters is the "heap memory" being used by the game.
