189677 - Images occasionally corrupt, as do file CRCs.

Status: RESOLVED DUPLICATE of bug 189689

(Core :: Networking, defect)

Description

[Mark Perris]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3b) Gecko/20030118
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3b) Gecko/20030118

When using the latest build (20030118), *occasionally* large images displayed in
web pages are corrupted. Pressing CTRL F5 will sometimes fix the problem, or
other times, when the image is initially correct, a CTRL F5 will give back a
corrupt image. The same happens for files. Some of the time, a ZIP file will
fail its CRC.

I have not seen this before on mozilla, so i dont think its a change my end. It
might be related to bug 176919.

Reproducible: Sometimes

Steps to Reproduce:
1. Find any page with a large image on (1280x1024+ i would suggest)
2. View that image
3. If it is not corrupt, hit CTRL F5

1. Download a large zip file
2. See if it fails CRC

Actual Results:  
Sometimes, much more than normally, the images and zip files are corrupt.

Expected Results:  
The images and zip files should not be corrupt

Have not seen this before, i do a lot of image work, and i have maybe seen this
once in 6 months, now its happening much more often, maybe 2-3 times a day.

Attachment: Example Corruption

From deskmod.com, although more sites will do it too, such as 
http://www.ojuice.net/pics/piclib.htm?OJ_PICLIB_REPpg=4, especially with a CTRL
F5 on any of the zoomed in pictures, from that page.

I should also add, i cannot reproduce this under IE6, just to rule out any
routee/proxy config probs here. You may have to CTRL F5 5 or 6 times to make it
show up, rather than waiting for it to occur randomly

isn't that a regression by bug 73322 ?

I'm seeing image-corruption too on http://www.belgium.be/ with a 20030119 build
on MacOS 9.2.2 I had to go back to an earlier build (20030116) to view this website.

very occasionally you might notice it happen on HTML too, a page will be
rendered incorrectly, or text is slightly corrupted, and requires a from server
refresh to make it work. It just seems to be random small errors in any
networking data that mozilla recieves. I am aware occasionally pages do not
render correctly for whatever reason, but this is a lot more common than it
normally is since builds dated 16th, and combined with the image problems,
suggests the idea of very occasional data corruption might be valid.

Might be related to bug 189689.
