  • Remote Extension/Connection Type: SSH

Steps to Reproduce:

  1. Have SSH configuration in VS code:
Host intermediate_host
  HostName XX.XX.XX.XX
  User mkulin
  ForwardAgent yes

Host final_host
  User mkulin
  ProxyCommand C:\Windows\System32\OpenSSH\ssh.exe -q intermediate_host nc YY.YY.YY.YY 22

  1. Connect to a final_host using VS code

  2. Observe high CPU usage. It is not happening if connected directly to final_host without proxying through intermediate_host. Also, surprisingly, it is possible to open, edit and save files.

The process that eats CPU:

I think that is the real error, version 'GLIBCXX_3.4.22' not found

Do you know if you have an older version of this available that was used in earlier vscode, do we require a newer version now, @deepak1556 do you know?

I could test vscode-server if you give me it built against GLIBC <= 3.4.21 for armv7l.

I see the same problem connecting from OS X to amazon linux Linux a-2zurb4h4bbny 4.14.203-156.332.amzn2.x86_64 #1 SMP Fri Oct 30 19:19:33 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux.

Is there any debug information I can provide to help resolving this?

It happens both when I use the ssh option or remote into a container on that Linux machine.

underlying issue is narrowed down in #2998, lets continue the discussion there.

This solves the 100% CPU issue.
Go to extension and mark this option 'off'.
