Description

  • Version: v7.6.0
  • Platform: Windows / Docker AWS POSIX 64-bit
  • Subsystem: V8 5.5 / zlib 1.2.11

We noticed steady and consistent memory leaks in our application when running in production using v7.6.0. At first we attributed this to a section of code using async/await but after reverting this code change the problem persisted. As soon as we reverted the node version used back to v7.5.0 in our Docker container the issue went away completey.

This mirrors the experiences of: https://twitter.com/yaypie/status/838539575605653504

I can provide additional graphs from Cloudwatch showing memory utilisation growing in our application if necessary.

I am surprised no one else seems to have found the same issue or raised it as an Issue or PR so far!

Stuck on v7.5.0 until this is rectified - which is a shame as we were looking forward to trialling async/await
