140857 - Javascript animation app not working

Status: VERIFIED DUPLICATE of bug 127825

(Core :: Networking: HTTP, defect)

Description

[Matt Foster]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.0rc1) Gecko/20020417
BuildID:    2002041711

The javascript image player at the above URL will initially load correctly, as
do the 9 images it loads, but after a period of time (minutes) the loop becomes
populated with duplicate images (e.g. frames 4-7 will all have the same image).
 I believe that eventually all 9 frames end up with the same image.  Also, I see
the status bar at the bottom of the browser continually switching between
"Sending request to..." and "Connecting to...".  Netscape 4.x loads the app and
9 images, goes to "Document Done", and does nothing further.

This may be one for Tech Evangelism, but I'm not 100% sure.  The js code appears
to be rather old (~6 years).


Reproducible: Always
Steps to Reproduce:
1. Load the above URL
2. Wait and watch as frames become populated with duplicate images


Actual Results:  Loop which should contain 9 unique images ends up as a loop
with many frames having the same image.

Expected Results:  Load the app and 9 unique images

I see no DOCTYPE when I view the page source, so that's why I think this may be
headed for Tech Evangelism.  However, it is *not* using layers or any other
common proprietary calls that I can see.  I'll let someone who knows more than
me make that determination.

I did not see the conditition of "all frames end up with the same image", and my
status bar text remained at "Sending request to ...".

I guess this may be a problem of cache mechanism ...

dom level 0 for triage

I notice these <meta> tags at the top; could they be part of the problem?

<META HTTP-EQUIV="Refresh" 
                 CONTENT="1200;URL=http://www.rap.ucar.edu/weather/satellite/">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">



If I let this site load for minutes in Mozilla trunk 20020428xx WinNT,
all my memory gets used up. I get a warning from the WinNT OS that I'm 
about to lose all physical memory : "please shut something down."

This is in contrast to NN4.7 and IE6, which both remain at a stable,
constant memory level after the 9 images are loaded...

I'm going to reassign this one to Networking for further triage; 
I don't think DOM is the right component -

I am seeing the same behavior (loop being filled with the same image after some
time) on my RH 7.2 machine.  In fact, I left the js animation running unattended
for a long spell (10s of minutes), and when I got back the browser had gone back
to the animation's "parent" page, http://www.rap.ucar.edu/weather/satellite

My cache preference is set to "Every time I view the page"...if that matters.

Changing OS to All

I stumbled on this looking at the Tech Evangelism Top 500 of all things...

I believe this bug is a dupe of Bug 127825.  The page referenced in that bug
uses the same js image player as the page I reported.
