- Subsystem: Stream, Console
Maybe this is related to how Node.js handles IO asynchronously, so it was not designed to handle this kind of code.
Execute the following:
var str = "Hello";
while(true) process.stdout.write(str);
or this code:
var str = "Hello";
while(true) console.log(str);
The node process starts eating memory (about 1.4 gigabyte in my case) and then it crashes with a heap out of memory error, see below:
FATAL ERROR: MarkCompactCollector: semi-space copy, fallback in old gen Allocation failed - JavaScript heap out of memory
