received one more explanation from siteground as to googlebot creating this problem, please read below
hank you for contacting our Help Desk center!
I reviewed the server-side logs carefully and noticed that increased resource consumption is caused by a huge number of hits from google bots towards your website, which you can see from the Webalizer tool in your cPanel under the "Top 30 Sites" section.
As a possible course of action you can block the IP addresses of these bots using the IP Deny Manager in your cPanel or at least decrease the bots' crawl rate significantly from your Google Webmaster Tools account, as explained in the following article:http://www.google.com/support/webmaster ... swer=48620
Alternatively you can upgrade your account to a more powerful solution, which will have the necessary resources to handle such an extensive indexing of the site by the google bots.
please help do something at the earliest, as any delay siteground would disable my website
