Confirming this bug exists. Strangely enough, it only started causing issues for me when I updated to VSCode 1.16. I had it installed and working previously without a problem. After I upgraded, VSCode started to freeze and after about 1min - it would crash.

Here's the odd thing - it only happened when I opened a PHP app repo I've been working with for months without any issues. Other projects didn't cause a crash. PHP project directory is by far the largest though, so that may be related.

Details:
VSCode version: 1.16 and 1.16.1
Platform: Mac OS X Sierra (10.2.6)
Steps to reproduce: For me, opening my really large PHP app.
Other Extensions: JSLint, ESLint, TSLint, PHP Extension Pack

@zignd The problem is that workspace.openTextDocument is used for all css & html resources in the workspace.
The VSCode documentation, unfortunately, lacks to mention it, but opening a text document is costly and has side effects: The document is passed across process boundaries to interested language servers where it is validated. Potentially lots of error markers are generated and end up in the problems view.
I recommend doing the following instead. For each resource:

• check the already open text documents and, if available, get the contents from there
• if not, acquire the file content with fs.readFile

If there is a need, we can look into providing additional API in VSCode to detect the language and file encoding. Please file issues! Thanks a lot!

Another confirm with a rather small size C++ project. Hang the main process.

VSCode 1.17.0 on macOS 10.12.6.

I guess this issue has been fixed in the latest update. Thanks to Erich Gamma for this great pull request #90.

This is still happening for me on Ubuntu 16.04, VS Code 1.19.2, latest version of the extension at time of writing.

With the extension enabled, VS Code will periodically crash, taking out my whole session. Running two copies of VS Code would cause that to happen within seconds.

With the extension disabled, I have encountered no problems over a period of several days usage, multiple instances of VS Code, moderately large projects.

Hi @mcquiggd, would be great if you could help me reproduce the crash. If you have some time, could you create a public repository or point me to one that causes the crash to occur? So that I can clone and open it a VS Code workspace.

Another thing, the crash is due to excessive memory consumption?
