Minecraft Exit Code 805306369
Your modded Minecraft crashes and the launcher shows exit code 805306369. It looks cryptic, but it almost always comes down to memory, the client ran out of RAM, or the JVM crashed, and the crash report tells you which.
What does this error mean?
805306369 (hex 0x30000001) is an abnormal-termination code the launcher surfaces when the Minecraft JVM dies. On heavy modpacks it most commonly means the client exhausted its allocated memory or hit a native/JVM crash, the log pins down the exact trigger.
Process exited with code 805306369
Most Common Causes
- Too little RAM allocated to the instance for the modpack.
- A 32-bit Java that cannot address enough memory.
- Too many mods / high-resolution packs exhausting memory.
- A native or driver-level crash in the JVM.
- A conflicting or corrupted mod.
How To Diagnose
- Check the RAM allocated to the instance in the launcher.
- Run 'java -version', confirm it is 64-bit.
- Open latest.log / crash-reports/ for a memory or native error.
- Note whether it crashes on big modpacks specifically.
Recommended Fixes
- Allocate more RAM
Raise the instance memory (heavy packs often want 6-10 GB), but leave RAM free for the OS. - Use 64-bit Java
A 64-bit JDK is required to address larger heaps for modpacks. - Read the crash report
Let latest.log / crash-reports/ point to the failing mod or the memory error. - Trim or fix mods
Remove a conflicting mod, or reduce mod/texture load if memory is the cause.
