371697 - high cpu/ram usage and crash when downloading files after no downloading for a few hours

Status: RESOLVED INCOMPLETE

(Toolkit :: Downloads API, defect)

Description

[david miles]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2

Upon opening a fresh browser, downloads work fine. When inactive for a few hours, starting a download or two will lock FireFox up and it will begin consuming 40-50% of CPU usage and anywhere from 500-1500 of memory (the amount of memory used is completely dependent on the amount of time since the lock up). This happens every single time, and I've went from 2.0 to 2.0.0.1 and now to 2.0.0.2 and it does the same thing. I haven't found anyone with similar problems, but I've not been able to remedy it.

Reproducible: Always

Steps to Reproduce:
1. Open fresh browser instance.
2. Download 100-200mb right away; this will work.
3. Wait anywhere from 2-6 hours, same instance of the browser open (possibly needing 5-10 tabs open, too)
4. Attempt to download anywhere from 2-5 files 20MB+ each at the same time. This will freeze the browser up, sometimes before even getting the 5th download started.
Actual Results:  
Browser locked up and the process needed to be ended manually.

Expected Results:  
Downloaded and saved the files like normal.

No error messages when crashing, just a lock up.

Did you try cleaning up your downloads manager?

works for me with Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9a6pre) Gecko/20070605 Minefield/3.0a6pre ID:2007060504 [cairo]

David, do you still crash with a latest release like Firefox 2.0.0.4 ?

If so, could you provide a Talkback ID (http://kb.mozillazine.org/Talkback)
