Description
Type: Bug
This was an annoyingly difficult issue to track down as due to the builtin typescript-language-features. I do NOT need to have this fixed as I can disable the extension. It would be nice to have fixed so I can run the stock builtin extensions. Posting here in case someone else has similar issue. They might be able to see a pattern with mine.
Reproducing
- In shell create new folder t1.
- Create file z.js with one line in it.
- Open code using remote ssh.
- Open folder t1.
- Open z.js in code.
Wait a few seconds. Get notification of:
Remote Extension host terminated unexpectedly 3 times within the last 5 minutes.
If I disable the buildin extension typescript-language-features then it loads with no issues.

I turned on typescript logfile with the following setting in settings.json:
"typescript.tsserver.log": "verbose"
I will attach a tsserver logfile from this. There is an exception there about executing command and message about "Error: write EPIPE"
I have tried both vscode version 1.89.0 and code - insiders. The vscode works okay in Remote SSH to other ubuntu servers. Just this docker instance has an issue. Remote (1and1 hosted) and local (docker hosted) installed similarly with ansible install scripts. There could be differences due to 1and1 hosted image vs docker initial image. (?)
I have tried disabling all extensions (Except Remote ssh).

Research direction
Reproduce the issue by opening a one-line z.js file in a folder over Remote SSH, then compare the Extension Host output with the verbose tsserver log. Focus on the reported SIGSEGV and EPIPE in the Docker-based Linux environment, and compare it with a working remote Ubuntu server. Done means the remote extension host no longer crashes with the built-in TypeScript language features enabled.
