Memory leak with zed window froze in Windows.

[blackbird314]

Summary

After leaving the Zed window and browsing some web pages, when I switched back to Zed, the entire window froze, and it showed the 'No Response' prompt. I checked the Task Manager, which displayed that Zed's memory usage was increasing at a rate of 5 Mb/s. I had to end the Zed process.

Steps to trigger the problem:

Currently, I am unable to reproduce this bug; it appears to be random. During the window freeze, I recorded the screen of Task Manager:

2025-03-19.173421.mp4

Zed had only opened two small projects, which usually occupied less than 200 MB. So I suspect that the memory leak had already been occurring for some time when the screen recording started.

Here is a portion of the zed.log I captured before restarting Zed:

Zed.log

Well, the same bug appears again today:

The zed.log shows same error:

2025-04-04T17:54:26.4529474+08:00 [ERROR] Error { code: HRESULT(0x80070718), message: "配额不足，无法处理此命令。" }

"配额不足，无法处理此命令" means "Insufficient quota to process this command" in English.

After ending the Zed process, I failed to reopen zed. The zed.log shows error when I try to restart it:

After restarting my laptop, I can open zed, and the whole log file here:

Zed.log

Arch Linux and got the same(?) issue

ZED 0.182.11 slowly fills the memory (1-2Mb/s) until it occupies my entire RAM (64gb)

• The memory leak starts off slow and then picks up pace
• Reproducible with default settings

Zed.log.old from when the computer froze:

This log entry is looping

Here's htop after ZED has been running for a couple of minutes:

Well, about several days ago, I meet the problem again: The window of Zed froze again, also it uses about 2000M RAM. However, the memory usage didn't increase infinitely this time, it decreased to normal standards quickly. And the Zed window returned to normal...

Ouch. I'm not super familiar with the profiling tools available on Windows.
Are you running debug builds or release builds (self built or from an unofficial source)

Moving this to a discussion because windows is not supported and isn't actionable.

I use community build version. And it looks like the problem also happens on Linux.

Also, according to #8436, the memory leak also happens on macOS.
