200633 - Duplicate Mozilla.exe process uses ~100% CPU

Status: RESOLVED WORKSFORME

(SeaMonkey :: General, defect)

[Victor Engmark]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2.1) Gecko/20021130

It seems that it is still possible to create duplicate Mozilla processes. When
my computer suddenly slowed down, I found a second Mozilla process in the Task
Manager which was using 95-100% CPU.

System / situation:
I have an AMD 1600+. Quick Launch is enabled. At the moment I had a few tabs
open at Mozilla.org to request new features and search for previously requested
ones, a second window with only a paused Flash presentation
(http://www.irider.com/demo/demo.htm), and the email / news reader.

The process continued this behavior when I closed the window with the Flash
presentation and the email / news reader. Nothing seemed to change when I
stopped the process in the Task Manager.

I tried opening the same windows again, but no second process appeared.

Reproducible: Couldn't Reproduce

Steps to Reproduce:
1.
2.
3.



Expected Results:  
No second process should have started, and it certainly should not use all the
CPU power.

When you use quicklaunch, you can temporarily see mozilla-processes : the old
one that is trying to shut down, and the new one that is still initializing.
Maybe in your case, your old process was never really stopped, and it was hung
in some kind of loop.

Since you can't reproduce this problem, it was probably a one-time thing.

REsolving as WFM until definite steps can be found to reproduce the problem.
