memory leaks - Why does an empty node.js script consume more and more RAM? -

-

running this:

setinterval(function() {     console.log(process.memoryusage()); }, 1000);

shows memory usage growing:

{ rss: 9076736, heaptotal: 6131200, heapused: 2052352 } ... time later { rss: 10960896, heaptotal: 6131200, heapused: 2939096 } ... time later { rss: 11177984, heaptotal: 6131200, heapused: 3141576 }

why happen?

the program isn't empty, it's running timer, checking memory usage, , writing console once second. causes objects created in heap , until garbage collection runs heap usage keep increasing.

if let go should see heapused go down each time garbage collection triggered.
