Upload et readfile() PHP

Hello,

It is not possible to upload files since I changed machine.

In made it is very long then the file that is uploaded is 0 bytes.

When I look Drupal logs this is what we find such messages:

Message
readfile(http://www.toto.com/sites/default/files/cl.doc): failed to open stream: Connection timed out dans /drupal/sites/all/themes/mytheme/views-view--dl-file.tpl.php à la ligne 22.

Message
Declaration of views_plugin_style_default::options() should be compatible with views_object::options() dans /drupal/sites/all/modules/views/plugins/views_plugin_style_default.inc à la ligne 0.

Do you have an idea of the problem?

My server is PHP 5.6.24 and version of Drupal 6

Thank you

Drupal version:
