Reconnecting and resource usage

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

  1. Recently I am having a big problem, when executing agents I frequently get “Reconnecting” and it gets stuck there forever. I don’t really know what it means but is it really trying to reconnect to something or it is just a mock word, because it never backs after entering this state?

  2. The second problem is that Cursor agents seems to be consuming too many resources of my machine. If I open 3 or 4 agents in parallel my pc soon frozes. It got worst recently and I am needing to restart my pc several times per day to solve it. And if I don’t use Cursor it never happens.

Steps to Reproduce

Use Cursor for a big task and multiple parallel agents

Expected Behavior

Agents should consume less resources and free them after finishing their job and they should be able to return from the “reconnecting” state

Operating System

Windows 10/11

Does this stop you from using Cursor

Yes - Cursor is unusable

Hi @MarceloDiani, thanks for the detailed report - sorry you’re dealing with both of these issues.

For the “Reconnecting” issue:

  1. Go to Cursor Settings > Network > Run Diagnostics and share a screenshot of the results - this will help us see if specific services are failing.
  2. Try switching to HTTP/1.1: go to Cursor Settings > Network, then set HTTP Compatibility Mode to HTTP/1.1, and restart Cursor.
  3. Which model are you using? (Auto, Claude, Gemini, etc.) We’ve seen some recent reports of reconnecting issues, particularly with certain models.

For the resource/freezing issue:

  1. Open the Process Explorer (Ctrl + Shift + P > “Developer: Open Process Explorer”) during a freeze and share a screenshot - this shows exactly which internal process is consuming resources.
  2. Try enabling the Extension RPC Tracer: Settings > Cursor Settings > Beta > toggle Extension RPC Tracer, restart Cursor, reproduce the issue, then Ctrl + Shift + P > “Developer: Open Extension Logs Folder” to check which extensions are consuming resources.
  3. As a quick test, try running cursor --disable-extensions from the command line to see if the freezing still occurs without extensions.

This diagnostic info will help us pinpoint what’s going on. Looking forward to your findings!

Relevant docs:

It’s very hard to use Cursor lately, this frozen bugs seem to happem only in IDE and in CLI it seems fine.

i could not share task manager with you because it really frozes everything and its happening even using a single agent, idk what to do anymore. I think i will keep using CLI as IDE does not work anymore.

My friend, maybe I noticed a cause of it. I had many old agents chats which changes were not accepted, so I think they were causing the IDE to crash. I achieved everychat and the changes were accepted because of that. It seems smothier now.
