I’ve been getting the same error for two days now. It crashes 2-4 times an hour now. Becoming unusable.
@Rich_Taylor temporarily try reverting to a previous version like 2.4 or 2.3. Cursor · Download
If it auto updates you to latest version, then be sure to have this editor setting set to manual:
Hey, this is a known issue on Windows. The renderer process hits the ~4 GB memory limit and crashes with that OOM error code.
A few things to try:
Check for an OTEL memory leak: Open the Command Palette Ctrl+Shift+P > Developer: Toggle Developer Tools > Console tab. Look for [otel.error] or OTLPExporterError messages. If you see them, that’s a known memory leak.
Rotate chats: If you’re running long agent sessions, start a new chat before they get too large. Long chat history is one of the main causes.
Monitor memory: Ctrl+Shift+P > Developer: Open Process Explorer. Watch the renderer process. If it climbs toward 3.5 to 4 GB, start a fresh chat.
Check extensions: Run cursor --disable-extensions from the command line and see if the crashes still happen.
Clear workspace storage (nuclear option): Close Cursor, then delete the most recently modified folder in C:\Users\<your-username>\AppData\Roaming\Cursor\User\workspaceStorage. This resets your chat history and layout.
Also, how much RAM does your machine have? And does this happen more often during longer agent sessions?
