VSCode freezing when adding folder to workspace while working on remote Linux machine

[ravitejapavuluri]

Type: Performance Issue

I have SSH host configured

1. When I click at the bottom left side connect to remote host and I can connect to the selected host.
2. Once connected to the remote host, click add folder to workspace, it freezes and doesn't quit. I need to end task task from task manager.
3. I sometimes ssh to the same machine with different users and work on the same folder.

Thank you for taking the time to open an issue. This sounds to be related to the Remote - SSH extension, correct? Could you please also follow the troubleshooting steps outlined here and report back?

I'm a bit confused by how the error message you shared (could not be established Canceled) is related? Could you please share the entire log where you see this message?

I ran into this similar issue too after last week's update. Verbatim had to force close windows that were freezing and broken. I just reinstalled using the latest version, issue seems to be messing. Likely something with your update package is broken.

[ravitejapavuluri]

Yes, this is from the latest update. My friend is also facing same issue. After connection to remote SSH, he cannot add folder to workspace. I cannot take the logs, it just freezes and I need to kill from taskmanager.

Could be from the SSH extension but not sure.

[jbiams77]

This is also happening to me and my team. Since updating to 1.92.2, when I have vscode connected over Remote-SSH extension, when I add a new folder to workspace, my vscode freezes.

[watarungurunnn]

Same here.

[Shahid279]

Same issue even with reinstall the issues persist, it only happens when adding second folder once the workspace is open with two folder adding third and more folder does not impact.

Temp Workaround:

1. Open an empty folder and create a new workspace, then add another empty folder, it will hang just kill it from the task manager and reopen it should open your last session and workspace with two empty folders
2. Now you can add more folders or remove them without any issues, make sure to always keep two empty folders in the workspace
3. Anytime you open your remote session open that workspace first which has two empty folders and work from there

[TedThemistokleous]

exact same behavior ^ and able to repo this. If it keeps occurring I seem to fix it by just doing another fresh reinstall.

Saved session seems to get around this entirely but still a pain if say, server goes down and have to switch boxes.

I ran into this issue too, after click "reload anyway" button, the window will not respond to any action, it can only be restored by forcibly exiting and then reopen window. Interestingly, the newly opened window is in line with expectations.

[zhaodiaoer]

some new discoveries: when i open a new window -> connect remote ssh host -> click "Save Workspace As ..." , the window will not respond to any action until connection reconnected, although there are no opened code project.

same here

I've been experiencing this for a few months now. Adding a folder to a workspace - or removing it - appears to visually do nothing. Usually, if I restart VSCode, I get two windows: One with the old previous state and one with the new workspace with the folder I wanted to add in.

This occurs over SSH to a darwin machine from Linux.

This appears to only occur the first time a workspace is "created". Adding or removing subsequent folders works just fine.

[sovietspaceship]

This also happens if you open a workspace in a remote ssh session. Possibly the most frustrating thing I've ever experienced in vscode. It works for a bit then completely hangs, even after reloading the window. The remote server just stops responding and must be killed.

Seems to memory related since it quickly exhausts memory of the remote system.

[josh-gleason]

I'm experiencing the same issue. If I wait a while after adding a folder to an empty workspace, then I eventually get a failure dialog and VSCode reconnects to the host. This occurs consistently if I add a folder to an empty workspace. Adding folders to a non-empty workspace seems to be fine.

Client: Windows 11 Pro
Server: Ubuntu 20.04
VSCode: 1.97-insider (same occurs on 1.96.2)
