1 year ago Out of curiosity I looked into the developer tools and noticed tons of unresponsive extension host warnings. Seems like it might be the fault of one extension (https://github.com/Gruntfuggly/todo-tree/issues/621#issuecomment-1341099401, https://github.com/Gruntfuggly/todo-tree/issues/495, https://github.com/Gruntfuggly/todo-tree/issues/433).
I find it surprising, though, that a misbehaving extension in an isolated process is able to prevent core functionality like "Go to file" from working.

1 year ago I'm having the same problem. I'm using a server together with @ireneluna22 who's been using vscode yesterday and logged out. Still there are a bunch of zombie processes:

When I logged in there was an vscode process running at 200% CPU (from my last login) which I killed. We both work via ssh. She directly does ssh -X with X forwarding (Irene, can you confirm) and I start vscode locally and then use the remote ssh edit.
vscode 1.74.0-1670 x64 as updated via the vscode on ubuntu 22.04.1 LTS which is installed on all of our computers.

1 year ago @sim642 can you follow the steps in https://github.com/microsoft/vscode/wiki/Performance-Issues#profile-the-running-extensions and attach the profile in this issue thread. Additionally, based on https://github.com/microsoft/vscode/issues/167320#issuecomment-1341107388 can you perform an extension bisect from the command palette with Help: Start extension bisect to help identify if an extension is causing this issue. Thanks!

1 year ago @berndporr from https://github.com/microsoft/vscode/issues/167320#issuecomment-1351998937 I don't see any zombie process, how did you confirm them ?

Can you provide the command line of this process ?
Side note, for your use case maybe our remote tunnels feature https://code.visualstudio.com/docs/remote/tunnels#_getting-started is a better alternative than x11 forwarding.

1 year ago Sorry I didn't log mine properly as I was in a hurry but a day later when I logged in there was a 100% process running by @ireneluna22 but she had logged out by that time. Irene, do you remember if you were in via "ssh -X" or via code's "remote ssh"?

Either way these leftover processes have been a pain for more than a year and for me the reason to revert back to emacs as working on a shared server is really a pain.

1 year ago @deepak1556 I for my part don't do X forwarding anymore and neither Irene now. I had a look at the tunnel and that looks like a super complex alternative which I don't have the time to look into. We both use "remote ssh" and that's the also the way I'm working with my raspberry pis. Why doing another workaround when there are probably again other issues? That really needs to be fixed. Our workaround is now much simpler: killall code before logging out. Sad, but it works! And sorry I don't have time to do deeper debugging at the moment.

1 year ago Just to clarify, you are seeing these long running processes on your server (not on the client ?) when running with remote ssh ? Can you provide the full command line of these processes next time the issue happens ?
berndporr
commented
1 year ago Yes. The long running processes are where our python code is being edited remotely so on the server and where "code" runs its server. The only commandline is "code" on the client ( a laptop ). Then clicking on remote ssh within "code" and editing remotely python scripts on the server. On the remote server these zomie processes keep running even after the client has logged out.On 20 Dec 2022 11:55, Robo @.***> wrote: Just to clarify, you are seeing these long running processes on your server (not on the client ?) when running with remote ssh ?

Type: Performance Issue
Recently it has become quite frequent that VSCode is very unresponsive (not finding files, not doing git operations, etc) while "idling" at 50%-100% CPU usage. I have noticed that every time this happens, VSCode has a bunch of zombie sh child processes that come and go. During git operations also zombie git child processes. Clearly, it is really stuck doing something that it cannot even handle and wait its child processes.
By the way, VSCode UI is not frozen during this: loading bars still animate, etc.
