Likely cause: Copilot's async bash sessions or detached processes accumulating over time without proper cleanup. Each mode="async" or detach: true command holds a PTY.

Describe the bug

Hello,

I only had 4 terminal tabs open. There's a copilot session I've been using for a while running a ton of processes and then suddenly I get these errors:

✗ Re-test shell
  $ pwd
  <exited with error: pty_posix_spawn failed with error: -1 (Unknown error: -1)>

This has been affecting multiple copilot sessions simultaneously. A restart was required to recover.

There might be a bug or a "pty" session not closing correctly.

Thanks.

Affected version

GitHub Copilot v0.0.400

Steps to reproduce the behavior

Not sure how this can be reproduced.

Expected behavior

<exited with error: pty_posix_spawn failed with error: -1 (Unknown error: -1)> For this to not be a problem

Additional context

No response

This has been fixed in v0.0.407, which included a node-pty update that resolved the file descriptor leak causing the pty_posix_spawn failures. Updating to v0.0.407 or later should resolve the issue. If you're still seeing this after updating, feel free to reopen.
