717724 - Closing Firefox results in 100% cpu after suspend, xpcom-shutdown on the JS stack

Status: RESOLVED DUPLICATE of bug 750454

(Core :: General, defect)

Description

[Jonathan Protzenko [:protz]]

Happens on Aurora (11.0a2 (2012-01-10) x86_64) and Firefox Beta (10b3). Both are on x86_64 (Debian testing, up-to-date).

STR:
- open firefox
- suspend/resume
- wait for a little while
- try to close firefox
- firefox takes 100% CPU

CallJSStack() gives

0 app_observe(aData = null, aTopic = "xpcom-shutdown", aSubject = [xpconnect wrapped nsISupports]) ["resource:///components/fuelApplication.js":1317]
    this = [object Object]
1 app_observe(aData = null, aTopic = "xpcom-shutdown", aSubject = [xpconnect wrapped nsISupports]) ["resource:///components/fuelApplication.js":694]
    this = [object Object]

Looks like there's zillions of observers registers for the xpcom-shutdown event. Does that ring a bell to anyone? If someone could tell me how to find out what's in gShutdown (see fuelApplication.js) I'd be happy to help.

Cheers,

jonathan

Does this happen if you disable all your extensions?
