Memory Usage at 174GB (Gigabytes)!

Describe the bug / provide steps to reproduce it

My mac complained it was entirely out of system memory, which seemed odd. Upon investigating, it turns out Zed was using over 174GB of RAM.

Now, my workflow may not be what you consider ideal, just as an FYI:

• I have 10s of editors open at all times, with 2 split sections, or 4 (in a grid)
• I have 3 main terminals open running my watch scripts for 3 separate app development environments, endlessly scrolling
• I have additional terminals open to run additional commands
• I have the assistant panel open at all times. I currently have 25 or so threads through the ChatGPT API
• I have Github copilot enabled

So, yeah, there's possibly an awkward memory leak in there somewhere. :)

Environment

Zed: v0.106.2 (stable) OS: macOS 13.6.0 Memory: 32 GiB Architecture: aarch64

If applicable, add mockups / screenshots to help explain present your vision of the feature

If applicable, attach your ~/Library/Logs/Zed/Zed.log file to this issue.

If you only need the most recent lines, you can run the zed: open log command palette action to see the last 1000.

open a phoenix project, start a server, leave the computer for a few hours and come back.

Just a fresh Phoenix project? Or does it need something else? Is the server started inside Zed in the terminal?

TBH I have put in zero time trying to recreate it. The other day was the first time I even put in the time to see if it was a solve-able problem. Again quit+reopen takes <1 second so it hasn't been a huge blocker.

I started using Zed when I decided to make a Phoenix project, so I've been using them exclusively since their mutual day 1. If this issue didn't start happening from day one, it was pretty early on.

I always have three terminal panes open inside of zed: one with lazygit, one with iex -S mix phx.server, and one that is just a terminal shell that I run commands/tests from. These run in the right pane.

I almost always have two files open side by side in the middle. <5 tabs per pane

Left hand side is sometimes the Assistant (although this issue predates me using the assistant).

I never have the file tree open (ever).

I went back one month and retrieved my dependency list (I've added a lot of complexity in the last month, but again, this issue predates those changes):

    ]
  end

So fairly fresh phoenix project. I don't think it's anything internal in the phoenix app, as my BEAM process never passes a few hundred megabytes
