Running Docker For Windows causes High System CPU utilization

[shawngib]

Expected behavior

Run Docker for Windows with normal CPU utilization.

Actual behavior

System Process runs t constant 25%+ CPU after starting DfW even after stopping DfW.

• System Process - ntoskrnl.exe!RtlClearBitsEx+0x1fa0 25+ CPU

Information

• Diagnostic ID from "Diagnose & Feedback" in the menu.
  56160023-9F47-4343-972F-7BF79976FD1B/2016-11-11_10-54-09

• a reproducible case if this is a bug, Dockerfiles FTW
  Start DfW

• page URL if this is a docs issue or the name of a man page
  N/A

• host distribution and version (Windows version, build number, etc)
  Windows 10 Enterprise Insider Preview Build 14967.rs_prerelease.161107-1700

Steps to reproduce the behavior

1. Install DfW beta
2. Run DfW beta

For those triaging the issue, this "appears" to be a Hyper-V related issue in the latest Insider Preview builds, and may not have anything to do with Docker. Someone with a non-preview system may be able to help verify.

I've seen this too - I'm no longer seeing it with 14971 which showed up yesterday

[mogest]

Can confirm I'm also seeing this problem as reported on 14965. Thanks for letting us know it's fixed in a later build, @friism.

[kamkie]

i have this same problem on 14971

[michaeldaw]

I am also seeing it on 14971.

[friism]

Yeah, I see it too now on closer inspection.

Pinging @PatrickLang and @enderb-ms for ideas...?

FWIW I see the same issue on three machines (all on fast ring insider builds 14971.1000). In my case the thread consuming most of the CPU is at (my include typos as I could cut and paste):

ntoskrnl.exe!RtlAvlInsertNodeEx+0x20b70

This is not related to Docker for Windows as I see the same issue when starting other Hyper-V VM after a reboot without starting Docker for Windows. I'm therefore closing this issue, but:

• it would be good to get a comment from @PatrickLang or @enderb-ms
• you may want to provide feedback via the Insider feedback mechanism
• I've posted a question on the insider forum here. You may want to "Me too" it or provide additional information.

Thanks for reporting

[friism]

Thanks @rneugeba

[treeder]

Did anyone figure out a way around this besides reinstalling non insider build of Windows?

[PatrickLang]

Did anyone open feedback and submit logs using the Windows Feedback tool on this? Once it's filed I can ping someone on the Windows Insider team to make sure it's triaged. I don't have any machines running 14971 at the moment

[PatrickLang]

Ah - found one "Hyper-V "system" still spinning CPU (one thread) now in RtlAvInsertNodeEx Build 14971"

If you're hitting this issue, search for and upvote it. in "Feedback Hub"

[treeder]

Good find @PatrickLang . Here's the direct link to that in Feedback Hub: http://aka.ms/T0a5bo

@PatrickLang thanks. Up-voted. I also provided feedback via the insider feedback thing yesterday. Let me know if you need anything else.

[PatrickLang]

We have a fix on the way for a future Windows Insider build. Not sure what the date or build number will be until it's out though.

[PatrickLang]

A new build was just released: https://blogs.windows.com/windowsexperience/2016/12/07/announcing-windows-10-insider-preview-build-14986-pc/ If you have problems, please go ahead and open a new issue on it.

[friism]

@PatrickLang fixed it for me!

❤️

[rn]

@PatrickLang thanks for the heads up. I can confirm that the update fixed the problem for me.

[Pjstaab]

Is there a way to force this build? Windows keeps telling me it might take a day or two to receive a new build but I still am not having any luck. I am on the insider fast ring.

[PatrickLang]

14986 was recently deployed to Windows Insider - Slow as well. Are you still waiting on it?

I think they will release an ISO here eventually, but it's still showing 14965.

[Pjstaab]

I'm definitely still on 14965. I get the emails saying new builds come out but I'm not getting any updates on my computer. I've unsubscribed and resubscribed to the channel too and have waited a few days.

[PatrickLang]

@Pjstaab I'm sorry it's not working out. Unfortunately Windows Update is out of my area of expertise so I don't think I can help with it here. The best option for finding a solution is to check posts here or create a new one: https://answers.microsoft.com/en-us/insider/forum/insider_wintp

[Pjstaab]

I'm not in a horrible rush, just though on the off chance that someone knew something I could kickstart it but it's not the end of the world.

[treeder]

@Pjstaab did you change to the fast ring of the windows insider builds? You need to do that.

[Pjstaab]

@treeder I've been on the fast ring, tried switching to slow for a day and then back to fast, nothing seems to work.

[propagated]

After installing docker for windows on windows 10 1607 (14393) I have a svchost.exe running at a constant 25% cpu. I've pinned it down to the windows management instrumentation service which is bound to the hyperV services i let the docker installer enable.

@Pjstaab @treeder any non windows insider workarounds to be had?

[jjloesch]

Same issue is still there using latest Win 10 ver 1709

[kratos4ever]

Hi, Any updates on this issue?

[wintercounter]

Same here.

[industrial64]

Issue persists = no resolution here ^ .

[maeglindeveloper]

Hi everyone, have the same issue with vpnkit.exe.
