Problem with FTP Transfer
I have a script I'm using for my file system which opens a remote file, opens an FTP connection to a server, and uploads the file to the FTP server. This works fine, unless there's a big file. The problem is that with a big file, it takes longer to transfer it. When the transfer passes a certain point(I'm not sure how long it is), it restarts. For example, if it's transferring a 50 MB file to the server, it'll be doing just fine until around 12-13 MB and then I'll refresh the FTP and it'll be at 1 MB, until it does it again. Here's the code:

PHP Code:
 $fp = fopen($url, "r");
if(!$fp)
    ErrorExit("Could not open file!");

// ...

DebugPrint("Now uploading to $path");
set_time_limit(1800); // 1800s = 30min
$beforetime = getmicrotime();
DebugPrint("Resource ID of FTP conn is $conn");
DebugPrint("Resource ID of file itself is $fp");
$status = ftp_fput($conn, $path, $fp, FTP_BINARY);
$aftertime = getmicrotime(); 


Any ideas?

About how much time would say between when you start the download and when it crashes?

Try local
Might try saving the URL to a local tmp file and then use ftp_put to upload that.

Maybe 5-10 minutes, closer to 5.

Try using the IP address in the url and see if it happens. I seem to remember reading somewhere that ftp functions have a problem resolving hostnames.

The FTP function is using a file pointer, not an actual URL with hostnames. I can't use the IP because the webservers' domains and IPs are the exact same(typing in the IP does not give the same results as typing in the host name).
