Please forgive the large amount of text... most of it is contents of the file that is uploaded and corrupted to show you what is going wrong.

We've recently built a new box with the following specs: RHEL 3, Apache 2.0.46, PHP 5.1.1

The problem is that the upload is being corrupted during the upload. To test it we uploaded a simple text file with line numbers in, begins....

1this is a test this is a test this is a test this is a test
2this is a test this is a test
3this is a test this is a test this is a test this is a test this is a test this is a test
4this is a test this is a test this is a test this is a test
5this is a test this is

.. and so on.... for quite alot of line. The php.ini can accept a large upload (8M), that is the only change in the php.ini (although register_globals is on too)

When the upload file is moved from the tmp_name to the correct location it is corrupted, see below. The lines are duplicated and there is a weird header at line 20.

We've tried it with difference browsers and get the same results. MSIE on Win and Mac, Mozilla on Linux and Safari on Mac all with the same result. The upload script is very basic and just prints the $_FILES array if any error or uses move_uploaded_file().... We tested this function seperately and it moves files fine.
