Hi
The CPU Usage of my Laptop goes to 100 % out of which mozilla is using 99%, this
happened when i had 2/3 mozilla browser windows open and was running for more
then 30 min, i noticed that the laptop was slowed down, so i checked the process
running and mozilla was using 99% CPU

Reproducible: Sometimes
Steps to Reproduce:
1.open 2 3 browser windows, i have mail.yahoo.com, and iseriesnetwork and
http://www.as400pro.com/TipsAPI.htm open in 3 windows
2. dont close the for more 30 min
3.

Actual Results:  
the CPU Usage went to 100%

Expected Results:  
CPU usage must not have reached 99% 

Some times in yahoo, when i press ctrl+f to search on page, the browser hangs

I don't know if this is related to my problem, but when running
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040113,
I get the same problem.   

Windows 2KPro SP3.  P4 512MB.  40GB System.  

I can be browsing and Mozilla would freeze.  I can be typing and 
Mozilla would freeze for a few seconds. (It froze a bit just now
when I was typing "I can be browsing...".

Basically I would be(just froze on "would") doing something on
Mozilla(mail/news/browse) and Mozilla would freeze (other
apps are not affected).  I go to the Task Manager and see
Mozilla taking up 99% of the CPU resource.   I don't think
it's a constant time internval.  Probably a couple of minutes
in between.

I get something similar (cpu usage 85-95%) when either composing or replying in
mail/news.

SeaMonkey 1.1a, Copyright (c) 2003-2005 mozilla.org <developer build>

Showed up in todays CVS (checkout finish: Sun Oct 2 18:54:38 EDT 2005)

Closing the compose window does not free the resources, requires complete exit
from application.

Slackware 10.2, i686

Configure arguments
--enable-application=suite --enable-calendar --disable-tests
--enable-extensions=default,irc,tasks --without-system-nspr
--without-system-jpeg --without-system-zlib --without-system-png
--without-system-mng --disable-debug --enable-optimize=-O2 --enable-crypto
--enable-default-toolkit=gtk2 --enable-xft --disable-freetype2 --disable-xprint
--with-pthreads

Does this belong attached here or should I submit a new report?

Using Mac OS 10.3.6, CPU usage will jump to from little to none to 70-90% after
a bit less than two hours at least when off line. Not dependent on what windows
are open. Condition exists even if both browser and mail client are closed. True
with SeaMonkey builds through 2005100710

Ashish - I was not able to recreate with your description and I observe no one else has.  I am closing this WORKSFORME.  If you are able to recreate the problem with a new, current version please reopen and update the bug.
I tested with Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8.0.2) Gecko/20060404 SeaMonkey/1.0.1


The other comments (Ed, Rinaldi, D Andrian) STM are not related to the reporter.  Note, given equal symptoms but different steps or circumnstances to create the failure, you may be better off looking for a better matching bug, and if you don't find one then create a new one with your exact description.

Rinaldi, I rather think your mail compose problem is probably fixed. I had experienced something similar in that time period and my problem is gone.

D Andrian - a rhetorical question - how do you cause your problem if "Condition exists even if both browser and mail client are closed."?  Sounds like a shutdown/close window problem, and there are several bugs to choose from, including ones that involve "offline".
