High Memory Consumption Leading to Process Being Killed by OOM Killer

[khaled-wsa]

Technical Details:

• OS: Ubuntu (Connected through SSH, from the cursor editor)
• Editor Version: 0.13.1
• Environment: MacOS 14.1 Beta (23B5046f) - MacBook Pro Apple M2 Max
• Node.js Process Path: /root/.cursor-server/bin/0.13.1-6a9b9ee2426e8c76377b9695e69edb2ae325d4a0/node

Expected Behavior The application should manage memory efficiently, preventing the system from running out of memory and avoiding process termination by the OOM killer.

Actual Behavior The application’s Node.js process is consuming excessive memory, leading to the system running out of memory and the process being terminated by the OOM killer. [The server suddenly lags and everything stops, and when I reviewed the logs this is what I found:]

-- I'm not sure if this is also caused by an extension I have that I moved with me from visual studio, but I just turned off 90% of my extensions and I'm waiting, if this behaviour is repeated, I will update this report.

Please let us know if the same thing happens with the extensions disabled. It will be very helpful. Thank you!

What version of Ubuntu are you running this on?

I'm not sure if this is also caused by an extension I have that I moved with me from visual studio, but I just turned off 90% of my extensions and I'm waiting, if this behaviour is repeated, I will update this report.

Any update?

0.13.4 included a change that squashed an edge case memory bug. Please let me know if you still see issues on or above that version!
