Thanks for the report! That crash is basically the window running out of memory and getting killed by the system. To figure out what’s eating it, can you grab a few things next time it happens?

  • Are you in the editor window or the agent window when it crashes (or both)?
  • Roughly how many tabs do you have open, and are you opening any really big files (huge logs, minified JS, JSON)?
  • Run Ctrl + Shift + P > Open Process Explorer and watch the memory utilization. Does one process suddenly start to use a lot? A screenshot when it’s high would be super helpful.
  • Try running Cursor with extensions off: close it fully, then launch with cursor --disable-extensions. Do the crashes stop?

I am in editor

I am in editor mode > and using cursor 2.5
I see only 1 tab open currently after my reinstalled version (Cursor had uninstalled itself 2x)

I do have 267 files here. Does that give a problem? They have all been solved so I guess I can click keep all but I think these are here for quick access only.

I just had a crash like 20 minutes ago. Yesterday I did have one or two as well.

Only extension I had installed was Remote SSH. It’s disabled now.

Clearing those 267 files would likely stop the crashes, since it appears to be the source of the leaked listeners. Could you give that a try?

We should still address the underlying crash issue, but first, let’s confirm whether this is indeed the cause.
