I’ve been developing Android and Flutter applications for years on my own computer. Over time, I’ve built numerous apps with the emulator running for hours—even days—and sometimes had as many as 20 tabs open simultaneously. However, I’m experiencing a serious issue with Cursor IDE. It seems to have a memory leak problem that causes excessive RAM usage. Despite having 24 GB of RAM, I notice that the memory consumption keeps rising exponentially, eventually overloading the system and causing the computer to freeze. At that point, I have no choice but to force a shutdown by pressing the power button, and this happens about 10 times a day.
This issue only occurs when using Cursor. Many forum posts suggest that developers should remove plugins, but I firmly believe that the problem isn’t caused by any plugins. I kindly urge you to release a more stable version of the IDE—one that resolves the memory leak and performance issues—because the current situation is becoming untenable.
There are no plugins, I even deleted the theme in particular, I even had to do this to use it, it is a completely plugin-free ide and I have this problem, I have seen many users living in the forum or in different places, your only answer is to remove plugins, but this solution is not enough.When I scan the application with Mem, ram leaks continue exponentially, I hope the developer team will solve this, I will wait for the next update.I said above that it was not due to the plugin, but again the same comment, I think you are sending messages without reading automatically.
New user to cursor but this is my exact experience and is a shame as I’ve been an avid user of JetBrains products for many years but finally took the leap only to be met with severly aggressive memory leak despite having no plugins.
I get about 30mins of use before the inevitable max consumption of 64gb of ram is reached. A hard reset of the machine has to be executed in order to regain control.
Please fix this I was finally starting to incorporate AI in my work flows
Dunno if im crazy but i feel like this started happening to me too. Never used to happen til around the time i started using cursor. does seem like some kind of memory leak situation, except it persists after i close cursor. Task manager on windows doesnt even show what is using RAM, just that it is being used.
My Mac gets completely frozen. It keeps consuming all the available memory and as soon as it touches 15GB+ I have to power off the Mac. This is very frustrating.
I kind of have the same issue:
Using cursor leads to full sys-freezes (no bluescreens, literaly freezes) quite often.
Also cursor AI-responses got unbelievable slow to like 5min per requests often.
Ive read about a possible mem-leak but for me:
i have 32gb ram and it crashes at ~15gb ram
its getting unusable and im gonna cancel my subscription and switch to other solutions i guess. I already disabled plugins but that doesnt help, how should i work with an IDE with python without python being installed in the IDE, its annoying. Also VSCode does not have this issue using the same python plugin.
I already re-installed the python plugin and disabled every other plugin.
Same problem here. It can rush RAM usage from its regular 1,5-5GB up to 30-40GB in no time at all. I even installed it, for testing purposes, on a VM with 32GB of RAM just to try it out and it gets PAINFULLY slow quite fast. Even if I restart it.
In my VM I have 1 extension in Cursor, the SSH extension (since all development takes place on one of 5 linux servers). Cursor hasn’t always been this resource hungry though. I’ll see during the weekend if it would make any change from the Linux version of Cursor instead. I suppose there is some easy method somewhere in the forum to transfer my projects and their progress to another Cursor installation, on another O/S, so I’ll just look those up.
I’ve experienced the same thing. I’m on Fedora with 40GB of RAM, and Cursor uses 4-6GB. After working with Cursor for a while, it sometimes freezes my entire computer when I give it a task. I never had this issue with vanilla VS Code. I’m using Zed now and works flawlessly.
