Failed to import database

Hi, I have problem importing database, I have cwp6 installed, I try to import a database and it gives me this error:

Script timeout passed, if you want to finish import, please resubmit the same file and import will resume.

Error in processing request
Error code: 414
Error text: Request-URI Too Large (rejected)
It seems that the connection to server has been lost. Please check your network connectivity and server status.
