assertion failure in src/node_worker.cc with large number of workers #31614

Description

@gireeshpunathil
  • Version: master, v14.0.0-pre
  • Platform: Linux 3.10.0-957.5.1.el7.x86_64 1 SMP Wed Dec 19 10:46:58 EST 2018 x86_64 x86_64 x86_64 GNU/Linux
  • Subsystem: workers

I was debugging #23277 and came across this:

$ cat bar.js

const { Worker } = require('worker_threads');

for (let i = 0; i < 10000; ++i) {
  const worker = new Worker(
    'require(\'worker_threads\').parentPort.postMessage(2 + 2)',
    { eval: true });
}

$ node --max-old-space-size=100000 bar

node[101402]: ../src/node_worker.cc:135:node::worker::WorkerThreadData::WorkerThreadData(node::worker::Worker*): Assertion `(uv_loop_init(&loop_)) == (0)' failed.

I guess this has to do with libuv failure due to lack of memory, but can this be better handled?
