I have recently got an email from my host telling me that my gallery install has been using up all of our servers cpu. I was on holiday when I got the email and the hosting has now been suspended :( This is the info that they sent me:

Top Process %CPU 93.3 /usr/bin/php
/home/mrmoon11/public_html/kucc/modules/xg2.1/index.php
Top Process %CPU 92.4 /usr/bin/php
/home/mrmoon11/public_html/kucc/modules/xg2.1/index.php
Top Process %CPU 79.2 /usr/bin/php
/home/mrmoon11/public_html/kucc/modules/xg2.1/index.php

If I can get them to unsuspend my site (I really hope I can!!!!), What should I do to fix this?

Is there anyone oput there who can help me... please?

Thanks in advance

Edit: They said it has been happeneing for the past two weeks, I've had it installed for about a year and a half and it has been fine, what is there which could have made it go wrong all of a sudden?
