Long time Cloning the database

[saatchi]

Hi,

3 days ago, I tried to make a copy of a database. Today when I go to a database manage page (another domain), in the header of the page I see this process:

Cloning the database db_name to the database bkup. You will be notified of the progress by e-mail (user@domain.com).

in the last 3 days and after start copy, I rebooted the server and also reboot psa service, but it's cloning, yet!

At the other hand, when I get a top report:

top - 09:21:04 up 18:32, 1 user, load average: 1.75, 2.18, 2.29

you can see that memory is used but we haven't any process in the top list!

OS: CentOS 6.2
Plesk: 11.0.9 Update #29

Is there any way to find the hidden process?
How can I stop cloning?
