How to troubleshoot failed uploads?

So a few times a day we get customers who have failed uploads. This is a LAMP server set up using Uploader Dual 6.5.19. Just this morning a customer tried to upload a single file 5 times in a row and it fails every time.

Here's what's in the $_FILES array:

Array
(
    [SourceFile_1] => Array
        (
            [name] => febmar_2010.psd
            [type] => 
            [tmp_name] => 
            [error] => 3
            [size] => 0
        )

)

$_POST["FileCount"] is empty if that means anything.

I *cannot* contact the customer to get them to turn on any client side debugging. I don't know if there's any other server debugging I can turn on to help troubleshoot. I don't see errors in the Apache/PHP logs. User's browser string sent is

Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)

I'll PM you the website now. Are you sure about the error 3 and the page you sent? The error is set in the $_FILES array which is set by PHP's upload process right? Not by the uploader. I thought the error 3 was this:

UPLOAD_ERR_PARTIAL

Value: 3; The uploaded file was only partially uploaded.

Thanks

Thanks for testing it. Yes it always works for me too in all kinds of scenarios but every day we get a handful or errors like this. Usually it's just one file so I don't see how FilesPerOnePackageCount will help. But I'll try it.

Can you confirm that you agree that error code 3 is this:

UPLOAD_ERR_PARTIAL

Value: 3; The uploaded file was only partially uploaded.

Can you think of any other way to troubleshoot this? Log files somewhere? Is there anyway to turn on server side debugging for the File Uploader?

Thanks

post_max_size is 1000M (1GB).

upload_max_filesize is 1100M (1.1 GB).

error_logging = E_ALL

Others

max_input_time = 1800

max_execution_time = 10800

memory_limit = 128M

file_uploads = On

We're often getting errors with just one file being uploaded so I very much doubt the file size is too big. I set up a development site on the same server and changed both of the above settings to 1M. We got a different error when uploading a file that was too big - $_FILES is actually empty. With the problem errors noted above I'm at least getting something in $_FILES but it shows the UPLOAD_ERR_PARTIAL error.

We have error logging set to E_ALL but I'm not seeing anything written to the error_log.

Thanks for your continued support - what else can we try? (Java console is on the client side right? I don't have access to that.)

So this is becoming more and more of a problem - at least 3 or 4 customers each day are seeing it. It's a variety of files and browser/versions. So I'm going to add some text to show when uploads fail - "Try turning on the java console and send us the output." A couple things on this:

1) I went through the instructions here:

http://www.aurigma.com/d.../iu/UsingJavaConsole.htm

I'm on Mac OSX 10.6.5 - there was no Apply Now button. I assume the changes were instant. But I did have to restart the browser to see the console.

2) Is there anything specific that we should tell people to look for? Any options for them to turn on?

I'm still thinking this is a server-side problem but hopefully this will help out. By the way, we do give people the option to use the regular HTML form input file upload and have never had a problem with those uploads failing.

Thanks
