OUT_OF_RANGE error when os.availableParallelism returns 1 #160
Description
I first noticed this when running the fastify tests. We have a nightly process that takes a few key modules, like fastify, and runs there unit tests on the platforms we support.
We were getting this error consistently:
RangeError [ERR_OUT_OF_RANGE]: The value of "options.concurrency" is out of range. It must be >= 1 && <= 4294967295. Received 0

at async file:///opt/app-root/src/code/fastify/node_modules/borp/borp.js:150:18 {
code: 'ERR_OUT_OF_RANGE'
While i don't have direct access to that testing machine to see what the os.availableParallelism function was returning, I was able to reproduce this inside a container. I'm using podman desktop(macos 14.7.5) and i created a new podman machine with just 1 cpu.
Inside the Red Hat build of Node.js container, i made sure that `` returned one, then I cloned fastify, and ran the tests like our nightly process and got the same error.
Below is the log of what i did:
