According to a thread on AMPHP GitHub issue page: https://github.com/amphp/parallel-functions/issues/22
On macOS, the ulimit is by default 1024.
In my case, upgrading that to ulimit -n 4096 as suggested, worked fine.
According to IBM docs: "ulimit sets or displays the resource limits on processes created by the user." More info.
