Download problem

[Marin]

Hello,
I'm using:
Apache/2.0.54 (Win32) mod_ssl/2.0.54 OpenSSL/0.9.7g PHP/5.0.4
MySQL 4.1.12
DocMan1.3RC1 (PHP based document manager)

I'm having following problem: file uploads OK, but problem occurs when I try to download or view the file.
After some innvestigation, I found out that only first 2MB od data is actually downloaded (exactly 2.000.000
bytes) resulting in corrupted files. (uploaded files are OK!)
I couldn't find that limit anywhere in my system. If the original filesize is under 2M, files are downloaded
and/or viewed correctly.
Firefox, Opera, IE6 - they all behave in the same way.
Win98, 2000, XP - the same

If I manualy fetch the files (bypassing DOCman), downloads is OK!

What am I missing here? I'm pretty sure it's PHP related, but I'm running out of ideas where to look.
Pls. help,
//Marin

Could this be a limit imposed by your ISP rather than your code? With it
being a solid 2000000 it seems possible. I haven't come across a php limit
communicating data across two servers in my work place and these
streams are much larger than 2M. I did this as an experiment to see if I
could come up with a better way to update remote servers, so I was working
with G byte tar-zip balls. (turned out to be far too slow for this purpose).

If it is that, I was going to suggest a way of breaking the file into
blocks with the file functions, but I am not sure how an ISP counts these
limits, it could be a limit in a single stream or a limit within a time
period.

Actually, it is not live system. I'm running it on local LAN. Thats what frustrates me even more.
It would be so much easier to blame it on ISP :) but since I'm responsible person in company....

How do you download the file? Do you just go to the file directly, or do
you use something like "getfile.php?id =yourfilehere". If you use the
second method, make shure you don't try to read the file-contents into a
variable before displaying it:

$content = join( "\n", file( $fileLocation ) );

because this will cause errors with the php memory usage. Use fopen and
fread instead to read small pieces and then print them reusing the same
variable.
Or if you use an output buffer, make shure it doesn't grow to big...

If you use the first method... I have no idea.
