JavaScript Heap Out Of Memory Error - Felix Gerschau Right-click on the table header of the Task Manager and enable JavaScript memory. For instance, Node.js dynamically allocates memory to objects when they are created and frees the space when these objects are not in use. There are two types of garbage collection.One is called scavenging and makes use of incremental garbage collection cycles to process only a part of the heap at a time.This is very quick in comparison to full garbage collection cycles, which reclaim memory from objects and variables that . So unless there's a memory leak in the Express or NodeJS source code, all signs point to this issue is not being caused by a memory leak. node --max-old-space-size=8192 server.js V8 is handling two main memory categories: Stack . Though promises alone don't go far enough. Open the example in Chrome, open the Dev Tools, go to timeline, select memory and click the record button. This automaticity is a potential source of confusion: it can give developers . This document will help you understand what the problem could be if you are experiencing latency problems with Redis.
