Memory Leakage com.docker.hyperkit

[Sebastianbrg]

NOTES TO FUTURE READERS OF THIS THREAD.
PLEASE READ THE WHOLE THREAD BEFORE REPLYING. IN PARTICULAR, PLEASE UNDERSTAND:

1. There is a bug in MacOS that it reports twice the amount of memory actually allocated.
2. It is normal that all the memory has to be reserved up front before any containers are running, because of the way that virtualisation works in MacOS Hypervisor.framework.

See https://docs.google.com/document/d/17ZiQC1Tp9iH320K-uqVLyiJmk4DHJ3c4zgQetJiKYQM/edit?usp=sharing for a detailed investigation on this.

Actual behavior

Memory leakage.

Information

I also get a memory leak

[sickness29]

Me too

[EduardRakov]

and me too :( also com.docker.hyperkit loads CPU very much

[Zabudska-Yuliia]

Me too

[iMerica]

See #178.

[gvbkr]

Yes this is happening on macOS High Sierra 10.13.6.

Docker version Version 18.06.1-ce-mac73 (26764)

This started happening after I updated the Docker version.

[ylor]

Seeing the same thing.

2.83GB being used without anything running.

Docker version 18.06.1-ce, build e68fc7a

[AnielloFalcone]

4.77Gb with no images and no containers on:
macOS: 10.14.1 Beta (18B45d),
Docker: 2.0.0.0-beta1-mac75 (27117),
Engine: 18.09.0-ce-beta1

[mkohlmyr]

Mac OS High Sierra 10.13.4
Docker 18.03.1-ce

Regularly consumes ~1.5GB while completely idle after startup.

[ x ] I have tried with the latest version of my channel (Stable or Edge)
[ x ] I have uploaded Diagnostics
Diagnostics ID: 01B9140E-D975-46AE-AEA6-442DC281FAE0/20181001181235
Expected behavior: Low memory use
Actual behavior: Doing nothing and consuming 5Gb of memory, it is also reported as the highest energy consumer on my system.

Information
Is it reproducible? Yes. Just start Docker on Mac OS Mojave
Is the problem new? Don't know, never used it on a different version
Did the problem appear with an update? Don't know, never used it on a different version.

MacOS 14 (18A391)
Docker Community Edition 18.06.1-ce-mac73 (26764)

Hope this helps.
