Is there an existing issue for this bug?

  • I have searched the existing issues

Required Troubleshooting Steps

  • I have followed these troubleshooting steps
  • I have tried both values of the remote.SSH.useLocalServer setting (more info here)

Connect Locally

It connects successfully

->

Whenever I try to close a VSCode window with an active remote SSH connection, I receive the warning:

Do you want to terminate the 5 active terminal sessions?

Even if I don't have any terminal sessions open. If I actually have created terminal sessions myself, the number will increase as expected.

This bug is also reported here, but the converation is closed: #10322, and mentioned here on SO without any comments: https://stackoverflow.com/questions/78989589/vscode-warns-about-active-terminal-sessions-that-do-not-exist

I have verified that the problem persists if I disable all other extensions and also if I kill the remote VSCode server and try again. The remote.SSH.useLocalServer setting makes no difference.

I have not yet been able to verify if the behaviour is specific to the server I am connecting to.

The only other remoteSSH settings I have in my config file are a custom install path (remote.SSH.serverInstallPath) and

"remote.SSH.remotePlatform": {
    "calcua": "linux"
  },
  "remote.autoForwardPortsSource": "hybrid",

Expected Behavior

I expect there to be no warnings about closing active terminal sessions if there aren't any.

Steps To Reproduce

  1. Connect to remote SSH server (linux-based HPC).
  2. Close window
  3. Receive warning about active terminal sessions.
