Partial download of picture

[kief24]

Hello,

Visitors downloaded some pictures who were not complete.
I tested it and had the same problem.
Only upper part of the picture was downloaded.
Not all pictures are like that , but somethimes it happens.
( see 2 pics in attachment )
I use 1.7.

Anyone has an idea how his happens ?
Thx

looks like server crashes?
did you check the error logs?

maybe it's the same problem,
when users tring to download big mp3 files?

how big are the images? (filesize)

If it's that problem you can use the search to find the thread that handles the problem with the mp3 problem.

files are between 100 and 300 kb.

i'll search in error logs

I checked the apache error_log and the /var/messages log but couldn't find anything that could lead to a problem.
Also, checked the uptime and load of the server:
21:52:30 up 16 days, 8:27, 1 user, load average: 0.77, 0.54, 0.48

So this looks fine.

Yesterday i downloaded 6 pictures at once with the album ( in zip )
2 pictures were ok, 4 were corrumpted.

So, are you saying only specific pictures get corrupted or its random?
Where can I see it?

[kief24]

it seems to be random

The 2 pictures above come from http://www.schoolplaten.com/kleurplaten-kleurplaat-afbeeldingen-axenroos-193.htm
"pauw" and "schildpad"

I've put the zipfile with corrumpted files i downloaded ( from lightbox ) yesterday here :
http://www.schoolplaten.com/temp/1142666592.zip
-> Check "tricolor3" in it.


another thing is that pages don't seem to load somethimes .... I have to wait and wait, and somethimes i get the message "can't find server". If i hit reload during or after the waiting, everything works fine again. Maybe this has to do something with it ?

It seems to be the problem in your download.php
whatever modifications you did that send Accept-Ranges and Content-Range headers (I belive its the mod that allow resume downloads), does not work properly, in the tests I've made, the received image was 1 byte too short.
So, the sollution - use fresh download.php

ok, that makes sense, i installed the "resume download mod" a week ago.

Thx a lot
