500 VS Code failed to load. timed out go home

[rafipiccolo]

after one day the server is always down, and the healthcheck says all is good... :)

curl xxx/healthz
{
  "status": "alive",
  "lastHeartbeat": 1616257100338
}

i get this message on the screen : 500 VS Code failed to load. timed out go home
the errors says timeout, but the timeout i see is very fast (<1 sec)
i have no error in chrome console except the error 500 on /

i have nothing in the logs, here they are :

Expected

working

Actual

500 VS Code failed to load. timed out go home

Notes

This issue can be reproduced in VS Code: No

I'm not entirely sure what's going on here - I don't run code-server in Kubernetes, but I've run code-server overnight, or with intensive tasks in the background, on my laptops with no issues.

Do you think it could be traefik?

[rafipiccolo]

Thanks for your reply.
This traefik instance runs around 60 other projects simultaneously on the same machine for dev purpose with success. There is no downtime. All is fine.

Only this error 500 every morning. Every night I run a 6 hour big script to do all sort of maintenance. Maybe vscode ran out of memory during this process and can't recover ?
Can I see debug logs ? How can I help. It's annoying to restart it everyday :)
How come the healthz route says it's ok ?
It's a standalone docker (no kubernetes)

[rafipiccolo]

I guess I will replace the health check to :

test: ['CMD', 'curl', '-fs', 'http://localhost:8080/']

Since the / returns a status code of 500 when it is dead it is a better health detector :p

Im still open to suggestions on debugging.

Or someone can close the issue.

VS Code is spawned as a child process when its page is accessed and if the handshake doesn't complete within 10 seconds you get this "timed out" message. So possibly this is related to resources although I'm not familiar enough with how spawns and Node's built-in IPC work to really say.

Maybe it's taking longer than 10 seconds except you mentioned it takes less than one second so that's quite strange.

Running code-server with --log trace might reveal more information, at least it should show if there are messages being sent and received between code-server and VS Code.

We should improve this error message. It's awfully vague. Perhaps there are some more checks we can add to see if the spawn really worked or not as well. It also sounds like VS Code is dying at some point, maybe there's something related to that which causes the next spawn to fail.

Adding a VS Code check to the health endpoint sounds like it could be useful. Right now it only checks if code-server itself is up but not VS Code.

Hello, currently using code-server in termux and getting the same 500 error. Here is my trace:

Ideas?

[jsjoeio]

Hmm... not sure what that could be. @leKamikaze1 do you mind opening up a separate bug report issue and providing reproduction steps? Then we can look further into your issue.

I have the same problem. Because I limit the docker container cpu to 100m. It worked when I set the cpu to 1000m.
