99645 - Mozilla in non-active JSPager desktop sucks 75% CPU

Status: RESOLVED INCOMPLETE

(SeaMonkey :: General, defect)

Description

[flyguy]

I am using JSPager in windows 2000 - http://hem.fyristorg.com/jspage/ - which
allows you to have virtual desktops.  When I have mozilla - Sept 14th Nightly -
open in one virtual desktop and switch to a different one, the cpu spikes to
100% with mozilla taking 75% and JSPager taking 25%.  The only reason I account
this bug to mozilla is because doing the same with IE doesn't cause this effect.

I tried this also with 

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.3+) Gecko/20010831

and it does the same thing.  Oh yeah I am using JSPager 2.5

Bug 80734 would seem to be fixed.  Since mozilla doesn't crash for me with 
JSPager on install or any other time so far.  

Added some people from the other bug, thought they might be interested that it 
was fixed.

This bug has persisted in all versions of Mozilla I have tested, up to and 
including 2001092503. It has been identified on Windows 2000 (5.00.2195, SP2)
and jspager v. 2.5 (http://hem.fyristorg.com/jspage/). No other applications
alter their processor usage after switching to a new desktop.

It appears that the bug is now fixed.  I don't see it anymore...  Seems to have
been fixed after Sept 17th.  I am using today's nightly build October 16th and
it seems to work.  Can anyone else verify?  Same version of jspager.

[Dan de Haan]

Seems to work fine here as well.  Using the Oct 4 Build.

Comment 7

[flyguy]

Seems to work for at least two of us.

I get the same old 100% CPU utilization behavior on:



JSPager 2.5 and 



Mozilla/5.0 (Windows; U;Windwos NT 5.0; en-US; rv:0.9.5+) Gecko/20011016

[flyguy]

Hmm...  do you have service pack 2 installed?  I don't have it installed.  I
have all other windows 2000 updates except I am using IE 5.5 not 6.

When I first reported the bug I might have had it installed.  

Here is my mozilla tag

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.5+) Gecko/20011016

What about you, Dan de Haan, what version of windows are you running.

I'll reopen the bug..  I might eventually reinstall service pack 2.

I have all of the Windows security updates, Win2k SP2, and IE 5.5 SP2.  Start::Settings::ControlPanel::System reports that I'm running Win 2000 5.00.2195 Service Pack 2.

It may be possible that I've improperly installed the daily build....
I still have 0.9.5 installed from the milestone release.  I unzipped the daily build into C:\Program Files\Mozilla.org\Mozilla\bin, and created a new shortcut to the mozilla.exe in that directory, with the "startup directory" pointing to that same directory.  When I click on the old shortcut, (i.e. c:\Program Files\Mozilla.org\Mozilla\mozilla.exe) I still get "0.9.5" and the new shortcut reports "0.9.5+".  Do I need to fully uninstall the 0.9.5 Milestone in order to use the daily or is the installation procedure I described sufficient to avoid conflicts?  

Comment 11

[flyguy]

Should be fine as long as you didn't unzip into a previous install.  When you
installed sp2 did you select the keep uninstall ability?  You might want to try
uninstalling sp2 and see if it still misbehaves unless you require the sp2 for
something specific, otherwise I'll get around to it eventually.

Comment 12

[Dan de Haan]

I have Windows 2000, no service packs.  It works fine.

Comment 13

[Asa Dotzler [:asa]]

Is this  still a problem then?

Comment 14

[flyguy]

I never got around to testing it again but I am pretty sure it still occurs if
you have w2k sp2 installed.  I'll see if I can't give it another try later today.

Comment 15

[flyguy]

Hmmm I just tried it on W2k sp2 5.00.2195 w IE 6.0.2600.0000 updates (q306121)
using mozilla 2001122703 and I didn't see the cpu spike behavior.  

Does anyone still see the spike behavior with the latest build?

[Asa Dotzler [:asa]]

flyguy, thanks for the follow-up. Feel free to reopen if this happens again.

Under Moz 0.9.8, windows 2000 SP2 5.00.2195, IE 5.50.4807.2300, I still have the
problem.

[Gregory A. Shimansky]

I use JSP pager 2.5. I tried mozilla 0.9.9 and then nightly 2002031803. In both cases after I open 
mozilla window and then switch to another desktop I see 60% of CPU used by mozilla, 40% of CPU used by 
JSP pager.

Using win2k 5.00.2195 with service pack 2 installed.

Reporter can You test using Mozilla Browser 1.7 and Windows 2000 SP3 and report
if You still have the problem? Thanks.

As reporter, I'm sorry, I'm not running windows anymore since a year. Can't
confirm the bug to be still valid for me.
