trouble uploading more than 500 bytes...

Hello, I have trouble uploading files to a server. Actually I can't upload more than 500 bytes or so. Here's a quick print_r of the $_FILES [_FILES] => Array( [avatar] => Array ( [name] => index.html [type] => text/html [tmp_name] => /tmp/phpRbmXK5 [error] => 0 [size] => 505 )) If I try bigger file (540 bytes or 2mb) it's simply return this. [_FILES] => Array([avatar] => Array( [name] => ajax-loader.gif [type] => [tmp_name] => [error] => 3 [size] => 0) ) error 3 is partial files sended. (By the way, there's no processing, only a print_r(); So here's my setup from the php.ini PHP Version 5.2.4-2ubuntu5.3 max_execution_time 1000 1000 max_input_nesting_level 64 64 max_input_time 1000 1000 memory_limit 999M 999M post_max_size 200M 200M upload_max_filesize 200M 200M upload_tmp_dir no value no value I run Apache/2.2.8 I checked the /tmp folder. it's empty, even if uploading really big file, same for /var/tmp. the permission seems to be ok (chmod 777). So, I'm pretty clueless about that one. Anyone have any insight about this ? Thanks, Karl. _________________________________________________________________
