### Where does the bug appear (feature/product)?

Cursor IDE

### Describe the Bug

Over long-running conversations with AI agents, Cursor starts to slow down, and eventually crashes. When this happens it is usually catastrophic, as I lose both the AI conversations I had open, as well as any plan documents that I had created in plan mode.

This happened just this morning. I spent most of yesterday in plan mode, having the AI explore a complex feature and write the steps for extending it. This morning I clicked “Build”. After thinking for a few minutes, Cursor crashed. When I reopened it, it was all gone.

### Steps to Reproduce

No immediate steps to reproduce. It happens after Cursor has been open for a while.

### Expected Behavior

Cursor needs to save conversation copies and plan documents locally and restore them in event of crash.

### Operating System

MacOS

### Current Cursor Version (Menu → About Cursor → Copy)

Version: 2.0.77  
VSCode Version: 1.99.3  
Commit: ba90f2f88e4911312761abab9492c42442117cf0

### For AI issues: which model did you use?

Happens with all of them

### Does this stop you from using Cursor

Yes - Cursor is unusable

hi @enragedcamel and thank you for the detailed bug report.

As this is not a common issue with a default installation we need further information to identify the cause.

- Please check Help \> Open Process Explorer and post here a screenshot. It would show if some part is using more memory or cpu than it should.
- Do you have any processes running in terminal within Cursor?
- Does this also occur on a new project? (would indicate large chat storage)
- Does this occur when you run with extensions disabled? `cursor --disable-extensions`

More info:

> **[Common Issues | Cursor Docs](https://cursor.com/docs/troubleshooting/common-issues)**

> Quick fixes for frequently encountered Cursor problems.

Note that you should be able to save the plan to a file from the main plan part in chat.
