Node.JS memory leak with PM2

Question

I was running my server with pm2 start ... and pm2 monit was showing me 3GB memory after 2 hours. So I attached memwatch, now I waited for

Answer 1

• I was also facing the same issue, but after little research i found that nodejs is not calling the garbage collector when using pm2.
• So, until PM2 fixes that issue temporary work around is force call garbage collector, using following

pm2 start app.js --node-args='--expose-gc'

Above argument --expose-gc will allow us to force call garbage collector from node js, now use following code for force garage collection.

if (global.gc) {
   global.gc();
} else {
   console.log('Garbage collection unavailable.  use --expose-gc '
   + 'when launching node to enable forced garbage collection.');
}  

This will solve PM2 meomry leak problem.
