Key Features of Zulu Platform x64:

• Low-Latency Garbage Collection (C4): Azul’s Continuously Concurrent Compacting Collector eliminates the "pause-the-world" stutters common in standard Java.
• x64 Native Optimization: Compiles bytecode directly into native x64 instructions for Intel and AMD processors.
• Superior RAM Handling: Manages heaps up to 512GB without crumpling (useful for those 16GB+ gaming rigs).

7. Troubleshooting Common Issues

Background: Why x64 matters for Project Zomboid on Zulu

• 32-bit limitations: Historically, many game builds (including older Java-based or bundled runtimes) were limited to 32-bit address spaces, capping usable memory near ~4 GB and causing out-of-memory issues for large maps, many simultaneous players, heavy mods, or long-running servers.
• x64 advantages: Moving to a 64-bit architecture allows the process to address far more RAM, improves performance of the JVM and native libraries in some workloads, and reduces memory churn from constant GC pressure on constrained heaps.
• Zulu runtime: Zulu is an OpenJDK distribution known for wide platform support. A Zulu x64 build brings a modern 64-bit JVM with security and performance backports, making it an attractive runtime for Project Zomboid’s Java-based server and client.

Docker and deployment notes

• Use official or community Docker images updated for x64 runtimes, or build your own with Zulu x64 as base.
• Example strategy:
  • Base image: adoptopenjdk:11-jre or an equivalent Zulu 11/17 x64 image
  • Provide environment variables for JVM flags and map host volumes for saves/mods
• For production hosts, ensure kernel settings (file descriptors, ulimits) and network tuning are appropriate for large player counts.

Testing and troubleshooting checklist

1. Backup: snapshot worlds, mods, and configuration.
2. Test on a staging server with representative player count and mod list.
3. Monitor:
   • JVM memory usage (heap, metaspace)
   • GC pauses (enable -Xlog:gc* if Java 11+, or -XX:+PrintGCDetails for older)
   • CPU and thread counts
4. Address common issues:
   • Out-of-memory errors → increase -Xmx, check mod memory leaks
   • JNI/native library load failures → replace 32-bit native libraries with x64 builds
   • Plugin crashes → check stack traces for architecture-specific failures

Recommended JVM flags and tuning (example defaults)

• Use G1GC for typical servers and clients:
  • -Xms4G -Xmx16G -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XX:+ParallelRefProcEnabled
• For very large heaps (≥32G) consider ZGC if Zulu build supports it:
  • -Xms32G -Xmx32G -XX:+UseZGC
• Enable server-class optimizations:
  • -server -XX:+UseCompressedOops (note: compressed OOPs only valid for certain heap sizes)
• Example command:
  • java -server -Xms8G -Xmx16G -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -jar ProjectZomboid.jar

Always monitor memory and GC logs and adjust.
