troubleshooting [Theme: Suffusion]

I am having problems with my websites exceeding CPU limits and have recently upgraded to VPS and still having problems. My hosts have come up with the following which does not mean anything to me, can you see if there is a problem please:-
WHERE wposts.ID = wpostmeta.post_id
AND (wpostmeta.meta_key LIKE ‘suf_%’ OR wpostmeta.meta_key LIKE ‘suffusion_%’ OR wpostmeta.meta_key IN (‘thumbnail’, ‘featured_image’, ‘meta_description’, ‘meta_keywords’))
AND wposts.post_status = ‘publish’ made by require, require_once, require_once, require_once, do_action, call_user_func_array, Suffusion_Framework->template, suffusion_query_post_meta
