Reproduce Steps

1. Create a project npm create rspack@latest
2. Create a script to compile consecutively with @rspack/core
3. Run the script to get memory leak

Script content:

const { rspack } = require('@rspack/core')
const config = require('./rspack.config')

function compile() {
    const compiler = rspack(config);
    return new Promise((resolve, reject) => {
        compiler.run((err, stat) => {
            if (err) {
                return reject(err)
            }
            return resolve(stat)
        })
    })
}


async function main() {
    await compile();

    setTimeout(() => {
        const memory = process.memoryUsage();
        console.log(`Total memory used: ${Math.round(memory.rss / 1024 / 1024)} MB`)
        main()
    }, 1000);
}

main().catch(console.error)
