即使我们将所有apache / php / server / mysql配置设置为高值，导入脚本也会停止

PHP Import Script is stopped even we set all apache/php/server/mysql config with high values

• before we had timeout from mysql we set timeout at 500
• than timeout from php we set timeout to 20000

max_execution_time = 20000
mail.add_x_header = On
upload_max_filesize = 3G
post_max_size = 8G
memory_limit = 8G

• than "Internal Server Error: The server encountered an internal error or misconfiguration and was unable to complete your request."

we set apache timeout at 15000 .Server is a 8 core 64GB ram server LINUX /PLESK Apache log, php logs, my sql logs have No useful info :/

What other we could do? Any Idea? thank you
