@JoshFerge thanks for reporting! I wrote a quick test that publishes 500 messages every 10 seconds but my memory usage never seems to go above 40mb.
Could you tell me a little more about your environment?
About how long on average does it take to acknowledge a message in your app? Are you running your application in GKE, GCF, etc.? How much memory is available to your application? About how long does your application run for before running out of memory?

Steps to reproduce
let topic = pubsub.topic( 'my-topic' ); let subscription = topic.subscription( 'test', { flowControl: { maxMessages : 20 } } ); let c = 0; subscription.on( 'error', function( err ) { console.error( err ); } ); // Register a listener for
messageevents. function onMessage( message ) { message.ack(); if ( c++ % 1000 === 0 ) { printMemoryUsage(); } }function printMemoryUsage() { let obj = process.memoryUsage(); console.log( 'Date: ' + new Date() + ', Memory: ' + Math.ceil( obj.heapUsed / 1000 / 1000 , 2 ) + 'Mb' ); }
subscription.on( 'message', onMessage );
