Importing products via the import tool

[bibob]

Hello sirs

Iam trying to import big amount of products via csv in the import tool.
The csv file have about 8000 products, but the problem is that, they only importing 200 of them and then it stops.

In the start i got the folowing google error page:

This site is not accessible(available)
Webpage on http://www.domain.com/adminX/index.php?tab=AdminImport&token=7981593d6f49cf may be temporarily down or it is permanently moved to a new URL.
Error 324 (net:: ERR_EMPTY_RESPONSE): Unknown error.

Then i added those to my .htaccess
# Max size upload file
php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300
php_value max_input_time 300


Then the website didnot go down more, but still loading after it import arround 190.
So after i have added that code upstairs the import imports arroung 190 even if the page still loading, so i think there is some limit in prestashop configuration.

i hop someone will help
thank you
