Cursor 0.5 and 1.0 constantly crashing (Ubuntu 22.04 LTS)

Bug Reports
1

I already reported this issue to [email protected] but I’m doing it here for transparency.

Operating system: Ubuntu 22.04.5 LTS (Jammy Jellyfish)
Versions of cursor I see the problem:

  • ./Cursor-1.0.0-x86_64.AppImage
  • ./Cursor-0.50.5-x86_64.AppImage

Other behaviour:

  • Cursor consumes a lot of RAM memory, it’s slow for any action, for example, saving a file takes around 2 seconds, creating a new file sometimes takes around 30 seconds, sometimes the agent stops working, the “connection fails” and I need to restart cursor to use the chat or for autocompletion.
    When cursor crash:
  • Randomly, lately when the agent is doing some work.

Hints from the logs (They are too long I can’t share all of them):
