PHP File Upload second file does not upload, first file does without error

So I have a script I have been using and it generally works well with multiple files...

When I upload a very large file in a multiple file upload, only the first file is uploaded. I am not seeing an errors as to why.

I figure this is related to a tim开发者_JAVA技巧eout setting but can not figure it out - Any ideas?

I have foloowing set in my htaccess file

php_value post_max_size 1024M
php_value upload_max_filesize 1024M
php_value memory_limit 600M
php_value output_buffering on
php_value max_execution_time 259200
php_value max_input_time 259200
php_value session.cookie_lifetime 0
php_value session.gc_maxlifetime 259200
php_value default_socket_timeout 259200
