Positron using a lot of memory - crashing

[davidjanmassgov]

Hi,

I've noticed in the past week using Positron that it's using a lot of memory. Sometimes it fluctuates between 1gb and 2gb + of working memory. It has crashed multiple times and I might have 1-2 data viewer tabs open as well as the Codex extension. I've removed all extensions that I don't use and it's still using a lot of memory and slowing down/crashing.

Are there any ways to troubleshoot? I know Codex uses a decent amount, but it's something I use daily.

It's not unusual for Positron to use a lot of memory (it's a big IDE!) but that's a lot more child processes than we would expect. Try running the Developer: Open Process Explorer command to see what's going on. Could you attach a screenshot of the result? Make the window wide so you can see the full text of every process and its arguments, if you can. Should look something like this.
