Edge browser 100% CPU, requires Force Quit (macOS Mojave and v91.0.864.48)
I'm reporting a problem I've experienced with Edge since I began using it six months ago. After using Edge for a few hours, it will begin using 100% CPU. According to the Task Manager, it is the "Bro...
What I do not understand is why the Edge task manager is not able to identify the specific tab or process responsible for the leak/spike. I will try to get a capture (running safari today), but when I had to kill edge yesterday, the process identified as "browser" was the highest CPU/Memory usage; none of the other tabs, add-ins or internal processes (pre-rendering, network service, storage, etc) even added up to the total indicated in the Edge task manager.
I've continued to submit feedback reports to Microsoft along with spin dumps and sample dumps. I am narrowing this down... after i close all the browser windows i fire up Browser Task Manager to look at the remaining Edge Tasks running. I have a browser task at 100% CPU, and i start killing off the other tasks until the Browser CPU drops. I'm seeing a pattern where i have multiple "Utility:Collections Entities Service" workers and one of them, after being killed, will allow the Browser Task CPU to drop down to 0. Seems like a bug somewhere in the Collections Entities Service, but of course, i'm not truly debugging this thing just narrowing down the scenarios.
