I'm having the same problem. It seems to have started yesterday when I was using Brackets 36. Upgraded to 37 and also rebooted, problem remains. It happens quite often, sometimes after 2 minutes, the last time after 30 minutes. I seem to have collected quite a few crash-reports on my system, I will try to attach them to this issue.

Edit: I can't find how to attach a zip-file. I have a zip-file with about 10 crash-reports regarding this issue sitting here. Here is a dump of the last crash (I checked the other crashes and they also show that the WebCore: Worker thread crashes):

Marking high priority - we should try to symbolize this stack trace.

@IjzerenHein - you can't upload zip files unfortunately, but maybe you could paste a few more stack traces into gists on gist.github.com and post links to them here. Thanks!

@njx - I've placed the crash dumps here: https://gist.github.com/IjzerenHein/9766462

@dangoor - it looks like this is in the Tern worker, so assigning to you.

@IjzerenHein - thanks!

@IjzerenHein Is it possible to estimate how many .js files are in your project, and how many KB/MB those files comprise in total? Do you have a large set of node_modules or any large minified JS libraries in your project, by any chance?

[IjzerenHein]

@peterflynn, Yes there are quite a bit of files, see this gist: https://gist.github.com/IjzerenHein/9773968

It basically consists of the ionic seed project:

Seems to be related to #7262.

After reading #7262, I took some screenshots of the activity monitor. It seems to be related to the Brackets Helper:

@ooJulien Can you please take a look at #7262 and see if the excluding directories workaround solves your problem too? It appears that it addresses @IjzerenHein's reported issue, but we want to hear from you before deciding how to handle this specific issue. Thanks!

[ooJulien]

@bchintx I am going to need some help to try this workaround as I do not know how to implement it in my project (beginner here...) :(

Not sure I am having the same issue on my side though: the only framework I am using is enchant.js and my main.js file was still small the first time I encountered this issue.

main.js:
enchant();
var game;
 
window.onload = function() {
       game = new Core(320, 320);
       game.onload = function() {
                  
       };
       game.start();
};

My project folder only includes three files: enchant.js, main.js and an index.html
I also managed to reproduce the crash with an almost empty .js file. I only wrote var one = 1; then waited for a few minutes before it crashed.

[dangoor]

@ooJulien Thanks for the details about your project. That will help, especially if I can reproduce what you're seeing.

Just to double check something: was the enchant.js the uncompressed enchant.js or is it enchant.min.js? I'm trying to reproduce the issue with enchant.js.

[dangoor]

So far, running release 37 on Mac OS 10.9.2, with main.js as above and enchant.js, I have been unable to reproduce the crash and I'm even getting decent code hints when I type game. within that window.onload
