Cursor IDE
After opening a project in Cursor, I get an OOM error code -568
Launch Cursor, open a project, wait a minute or two.
Cursor doesn’t close unexpectedly.
Windows 10/11
Version: 2.6.0-pre.30.patch.0 (user setup)
Yes - Cursor is unusable

Hey, thanks for the report. OOM crashes on Windows are a known issue. The Electron renderer process hits the memory limit and crashes.
A couple of quick questions so we can understand the scope:
Does it crash right when you open the project (without using Agent chat), or only after you send messages in chat?
Can you reproduce it on the stable build (not Nightly)?
Workarounds to try:
If you use Agent chat, rotate chats. Don’t keep very long sessions, start a new chat when the current one gets large.
Press Ctrl+Shift+P then Developer: Toggle Developer Tools then open the Console and check if you see lines like [otel.error] or OTLPExporterError. If yes, that can be an extra memory leak.
Press Ctrl+Shift+P then Developer: Open Process Explorer to track which process is using the memory.
Since you’re on Nightly, please try switching to the stable branch and see if the issue still happens. That’ll help confirm whether this is a regression in 2.6.0.
The team is aware of this issue. Let me know the answers to the questions above.
1 - crashes when i open the project, no agent chat is loaded, i just wait two minutes after opening and it crashes, there’s no action on my part.
no otel or otlp console errors
nothing seems to spike memory usage, it tripped around 1.5GB RAM usage
2 - changed to the stable build (details below), no OOM error on initial project load
Version: 2.5.20 (user setup)

Well it looks liek you’re not on 2.6 rather 2.5.20, but I am on 2.6.x and oom crashes a plenty.
Version: 2.6.0-pre.33.patch.0 (user setup)
Correct; following the instructions provided, I downgraded to the stable build from nightly, which solved the problem.

oh I’m stupid, I missed that part lol. ok ok so that one works for you, I might have to try that… Thanks!
I just checked on this, the stable build does not crash but the nightly build is still crashing with the OOM error.
Version: 2.7.0-pre.1.patch.0 (user setup)
Now getting the OOM error on the stable build
Version: 2.6.11 (user setup)
Latest stable build update is still throwing the OOM error.
Version: 2.6.12 (user setup)
So is this something I can expect to get fixed? Or should I just cancel my sub bc this is unusable?
Tried running with gpu disabled and extensions disabled, still getting the OOM.
Canceling my sub since it appears there’s no fix in sight. Really disappointed
Version: 2.6.13 (user setup)
Checked again after the update this morning, still failing.
Version: 2.6.14 (user setup)
It may be resolved? I was able to open the repo and complete a chat session today for the first time in a week
Version: 2.6.18 (user setup)
