Python Language Server uses too much RAM / Memory

[nojvek]

Environment data

• VS Code version: Version 1.27.0 (1.27.0)

• Extension version (available under the Extensions sidebar): 2018.8.0

• OS and version: Mac Snow Leopard

• Python version (& distribution if applicable, e.g. Anaconda): Python2

Honestly there should just be a command that generates this

Actual behavior

Machine crawls to a halt. Using Python's language server using 30GB+ happens after a couple of hours of use.

Expected behavior

Sonic like universe. FAST!

Steps to reproduce:

1. Use vscode with python for a while. We have a somewhat large repo with 10k+ python files.

I have the same issue with VS Code version 1.27.2

Cause to VS Code not responding...

Same here and unlike #2553, I have jedi disabled.

Same here.

I use vscode as git editor and also as mergetool.
My git config:

# .gitconfig
[core]
    editor = code --wait
[difftool "vscode"]
    cmd = code --wait --diff $LOCAL $REMOTE
    keepBackup = false
    trustExitCode = true
[merge]
    tool = vscode
    conflictstyle = diff3
[mergetool "vscode"]
    cmd =  code --wait $MERGED
    keepBackup = false
    trustExitCode = true

After each merge conflict fixed in vscode, the server seems to not release the used RAM.

The python extension is using nearly all my memory on my desktop computer, too. Task Manager says memory is eaten up by Microsoft.Python.LanguageServer

I have same issue on Linux Mint 18.3 with VS Code Version: 1.27.2 and extension 2018.8.0. After some time it uses all the RAM and starts flooding swap.

For those of you bumping up against this, a reminder that setting "python.jediEnabled": true in your settings will switch you back to Jedi and off the language server.
