A question about node memory management. I have (see below) a very simple
bit of code that, when run, slowly increases it's RSS usage forever.
I've tried setting variable to null and deleting variables - no effect.
Adding or removing the nextTick has no effect.
It just sits there, running and slowly eating RSS. heapUsed goes up and
down as garbage collection occurs.
Am I missing the point somewhere? why would asimple program like this
start with an RSS of 8-9 MB and over the course of 5 minutes have the RSS
grow to 12.5MB and continue to grow from there?
var memInfo = {
rss: 0,
heapTotal: 0,
heapUsed: 0
}
var timer = setInterval(function () {
process.nextTick(function () {
var mem = process.memoryUsage();
if (mem.rss > memInfo.rss) {
memInfo.rss = mem.rss;
}
if (mem.heapTotal > memInfo.heapTotal) {
memInfo.heapTotal = mem.heapTotal;
}
if (mem.heapUsed > memInfo.heapUsed) {
memInfo.heapUsed = mem.heapUsed;
}
console.log('Latest', process.memoryUsage());
console.log('Max ', memInfo);
});
}, 1000);
