What are the server specs running this? VPS / dedicated? If VPS, is it OpenVZ/Xen?

VPS 1.5G RAM OpenVZ

Well, it's strange that it's doing it after making a post - but OpenVZ with a "usual" load of 2~ worries me a bit. Your provider could be overloading the actual node it self, causing a bit of an issue.

How busy/popular is the site you're running?

My site is 3xupdate.com
If you have time please take a look. Thanks !!!

Going on your site doesn't really help all that much I was just wondering if your site was popular in the sense that it's causing the high loads itself, or whether the "high" idle load was an issue on the node.

Can you please explain more ?

How many "hits" / pageviews are you receiving per day? Are lots of people on your site at the same time?

If you're not getting many pageviews and have 1-2 people online at once then I'd be pretty worried and say there's a good chance that the node your on has quite a few people on it since a near idle VM shouldn't have a load average of 2.

Thanks for your answer.
Around 100K pageviews per day
70-200 visitors online at the same time.

Have you optimised your database etc? I'm still feeling that 2 is a bit too high for that site - how much are you paying out of curiosity?
