it should still fix some issue This issue is fixed and the change is pushed into npm repo. please get the latest version (1.0.25). for giving details which helped us isolate the problem.
As a side note... Growth of memory during execution in node.js should not be a concern as long as it does not cross the default limit of a node.js process after which the process will crash. We typically see the memory growing steadily initially and stabilizes near the limit. The default limit is 1G on a 64-bit machine which can be extended to 1.7G. Read this for more info.

like below fixes the issue Memory is allocated for the numbers Array, but I don't see any memory leak here. Garbage collector does not have to run as soon as there is something to claim back.
To illustrate my point, if you will increase length of the Array to help GC start collecting memory faster (also some minor tweaks)
code :
function getRandom()
{
  var numbers = new Array()
  for (var i = 0; i < 100000; i++)
  {
    numbers[i] = Math.floor(Math.random()*100);
  }
  return numbers;
}
function handleMessage(req,res)
{
  var body = '';
  req.on('data', function (data) {
    body += data;
  });
  req.on('end', function () {
    var response = new Object();
    response.numbers = getRandom();
    res.end (JSON.stringify(response));
    response.numbers = null;
    response = null;
  });
}
module.exports.handleMessage = handleMessage;

To fix this issue When I see this right this was fixed in v5.9.0, see this PR. It appears that in those cases both node core maintainer nor programmers can do much - that we pretty much have to wait for a upstream fix in v8.
So no, you can't do anything more about it. Catching this bug was good though!

To fix this issue It sounds like the garbage collector is running after you check the usage. Basically every once in awhile it will check to see if there is anything that isn't tied to anything anymore and will remove it, freeing up space. See this article for more details:

Hope that helps So, I resolved the issue by compiling to es2017 instead of es6.

I hope this helps you . You may not be experienceing a memory leak, but may just be constrained by the memory available.
The default instance class of App Engine has very low RAM (128Mo). You can try to increase the imstance class to at least F2:
