java.lang.StackOverflowErrorHow to Fix
1
Add -Xss4m to your JVM arguments
2
Remove recently installed mods or plugins that may cause recursion
3
Check data packs for circular function calls
4
Remove deeply nested command block chains
5
Review server logs for the stack trace to identify the problematic mod
Common Causes
- Infinite recursion in a mod or plugin
- Deeply nested command block chains
- Circular references in data packs
- Stack size too small for complex mod interactions
Diagnostic Steps
- Read the full stack trace to find which mod or class is repeating
- Increase stack size with -Xss4m
- Disable suspected mods and test
- Check data packs for recursive function tags
FAQ
What causes a StackOverflowError?
It happens when a method calls itself endlessly (infinite recursion), filling up the call stack. In Minecraft, this is usually a mod bug.
