Do you have "python.autoComplete.extraPaths" defined?

[PushUpek]

I have the same issue, but only with python2

[VelizarVESSELINOV]

@brettcannon only in the default user settings defined as []

[VelizarVESSELINOV]

It is the biggest CPU consumer of all the processes: >21 hours

Side comment that maybe it is the case of @PushUpek I have a lot of files and folders in my current folder that is not Python code or libraries, questioning if Microsoft Python Server is not trying to parse GiB of data continuously in the current folder of VS Code project.

+1 - I have the same problem with

VS Code 1.29.1
Microsoft Python Language Server version 0.1.65.0
Python Extension 2018.11.0
Python 2.7.15 (venv-based environment)

My python.autoComplete.extraPaths setting is also []. I tried to disable Jedi and Linting. I keep killing the process to keep my Macbook's fans from spinning, but it always respawns at 100% CPU usage.

Is there any way to disable the language server? I believe my only option right now is to disable the python extension completely.

This happens for me too. Python 2.7 with a moderately big project. What Info can I provide to help debug this?

[brettcannon]

I have moved this issue over to the python-language-server repo. Please report details/issues there.

[qubitron]

@brettcannon is this different than #2838?

[brettcannon]

@qubitron not sure, hence why I'm playing it safe and just reporting it up to python-language-server to decide if it's somehow different.
