Visual Studio Code Remote Development crashing AWS instance

Question

I came across Visual Studio Remote Development crashing a AWS instance and i'm hoping to solve this by increasing the instance memory. I have not tested it out yet.

Connection is ok and I can do Remote Development with no problems but only for a few seconds.

I am using Visual Studio Code Remote - SSH 0.51.0

Anyone experiencing this?

Answer 1

Yes, this is a current issue. The size of the EC2 instance does not matter. At this very moment, vscode 1.46.1 just took down one of my m5.xlarge as I typed this comment. You don't need to interact, vscode will crash/hang your instance with out any effort on your part. This comment comes on the heals of many attempts/configs/adjustments/distros (cento/ubuntu) and also waiting for the next stable/nightly builds, only to observe the same effect in all cases. This is a very large issue, for now work needs to continue with the old tried and true ssh tools, I hope MS can jump in here and fix it up or show us our mistake.

• Ubuntu 20.04
• VScode 1.46.1
• Remote SSH v0.51.0
• OpenSSH_8.2p1 Ubuntu-4ubuntu0.1, OpenSSL 1.1.1f 31 Mar 2020

I had the same issue when working with my Typescipt project on EC2. Here is an answer that solved the issue for me: https://github.com/microsoft/vscode-remote-release/issues/2692#issuecomment-852548425

If you are working on a typescript repo, I suggest trying the same:

Quoting the original answser:

I had the very same problem with VSCode connecting to my EC2 instance. However, this wasn't the first time that I had VSCode running with an EC2, and the other server that I had, was running smoothly. What was the difference between my old server (that is actually still running) and the new one? That in the old one, I was running an Apache server with only PHP code, so basically, I was only using VSCode for setting files and PHP.

I created a new server, started writing PHP again and everything was going fine. The problem came when I started writing JS code in a Node.js, and suddenly became very slow and began crashing, just with the same symptoms described above.

So, it looks like VSCode has an extension built-in in a release called "TypeScript and JavaScript Language Features" but you can find it easily by looking at the extensions box and writing: "@Builtin typescript". Find it and disable it and you'll be just fine.

However, it has downsides - mainly the coding experience would suck after you disabled the tool.

So Here is another way that is worth a shot:

According to https://github.com/microsoft/vscode-remote-release/issues/2692#issuecomment-901643826, VS Code Insider solved the issue.

So, try to download and use VS Code Insider: https://code.visualstudio.com/insiders/

UPDATE:

Nah, VS Code Insider did not work for me. Disabling "TypeScript and JavaScript Language Features" definitely worked, at the cost of shitty coding experience.
