This issue has been tracked in several places recently, with very vague responses. This week, without any update, foreground commands suddenly started timing out. My team uses various scripts that can run for more than 10 minutes, sometimes 30 minutes or more. This completely broke our productivity…

If this is a bug or system issue, I suggest reporting it in the Bug Reports category or emailing hi@cursor.com . Based on my experience, some issues come from the environment. In my case, I had network errors because my company uses a proxy. Sometimes I need to switch Network mode from 2.0 to 1.1 or…

Hi @Naufaldi_Rafif , we don’t have proxy or special env system manipulating requests. I suspect A/B testing or feature flag controlled behavior here, but not controlled correctly from the cursor team or there provider, on the same cursor version a collaborator have a totally different UI. Cursor t…

My Cursor editor is so buggy that it usually crashes every 15–30 minutes, and the agents can no longer get much of anything finished because they crash every 5–10 minutes. At this point, I have no choice but to cancel the Ultra plan and switch to Claude Code, since work is not getting done.

Cursor stability has never been a strongsuit, but it’s been especially abysmal lately. ‘Rules’ and other features are constantly in broken states without disclosure, tool calls and sub agents freeze and timeout. Needs restarts a couple times a day because of threads that will get bricked. And Cursor…

I am in the same boat. Cursor seemed to be working well for me before the new year. Terminal commands ran in the shared terminal space with agents able to both read and write to the terminal, browser integration worked, agents were able to run ssh/scp commands successfully. Now I’ve spent the better…

Well I had to revert Cursor to last stable 2.3 revision so my agents do not trip over this new "sandbox” feature added out of nowhere, without notice.

@Jacob_Stucky You describe exactly the issue we’re facing. I don’t know what’s happening inside the Cursor company, but they seem to be following a “move fast and break things” strategy. I hope this is only a temporary phase of their product, because professional development teams need stable tools…

I’ve been using Cursor for the last year and a half, and this kind of pattern where the Cursor team ships 5 updates per day every day with lots of instability has been very common as long as I can remember. I stopped using Cursor a few weeks ago, but I came checking back on this forum to see how thi…

It probably come from the sub-agents timing out when the model’s juggling too much context or hitting server-side glitches. It disrupts everything, right? Maybe try sticking to simpler prompts or restarting the session fresh to avoid the pile-up; could keep things moving until they roll out a fix.

I use Proxy (it is a good quality proxy I built myself, been using few years, dont think it is the problem) Cursor rencently really unstable on both Linux and Windows for me (both proxy env), sometimes chat finishes multiple times or just keep refreshing every 10 sec or so, eating my later prompt a…

Been there, done that…

At some point, updating Cursor is mandatory for using the agent: Mandatory update
