Memory Limit Exceeded Error in Java and JavaScript

[jeewoo1025]

Dear Authors, (@Jackal1586 @sbmaruf )

Thank you for your excellent work on this project!

We encountered consistent "MEMORY_LIMIT_EXCEEDED" errors when executing Java (Java 17) and JavaScript code, while other languages like Python and Rust ran successfully. Could you please advise how to resolve this issue?

The problem occurred during execution of the xCodeEval/prog_syn_val.jsonl file (Program synthesis - compact version).

📢 Note: We tried increasing Java’s memory limit to 4096MB, but the error persists.

...

Java 17:  
    nofile: 4096 
    nproc: 2048
    memory: 4096MB

Questions for Clarification

Could the observed memory usage (~2.48GB for Java, ~75MB for JS) exceed the configured environment limits?

Thank you for your guidance! 😊
