connection reset when uploading large files


I'm having a problem with my upload handler.  If I send small files (under 1M or so), it works fine.  if I send larger files, I get the following error in Firefox:

The connection was reset.
The connection to the server was reset while the page was loading.

When using Internt Explorer, the error is simply
The Page cannot be displayed.
The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings

Do I have a problem with my php.ini settings?  I've tried a few adjustments but can't find the magic solution.

Any ideas?

Thanks in advance.

Php has a set time out limit (default is 30 second)

I'll try that, but the timeout occurs INSTANTLY ... so I'm not sure how that affects things.

Just tried setting max_execution_time to a ridiculously high value, but once again, the error displayed immediately.

Check your upload_max_filesize

upload_max_filezie set to 200M

post_max_size = 250M
OK! what about the script, is there any upload limit set within the upload script?

Not that I can see ... here's the complete code:

if ($customer == "" || $contact == "" | $contact_email == "") {
print <<< END
<table width="500" border="0" cellspacing="3" cellpadding="3">
    <td width="65"><img border="0" src="UsseryLogo.jpg"> </td>
      <h1><font size="+3" color="#990000"><i>Oops.</i></font></h1>

else {

Script seems alright.

This is what I dug up from Firefox

The connection was reset
The connection to the server at %address was reset while the page was loading.

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any addresses, check the computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

You might want to investigate some more on this.
