VPS Server Load 6.0-8.0!

[TheInsaneManiac]

My host told me about 3 days ago that someone on my VPS was abusing their memory and it was causing me to jump, but today I get an email saying I've also been using excessive amounts of memory. My server load is anywhere from 6.0 to 8.0 when it's suppose to be in the .XX region. It's retarded I have disabled all of my heavy mods, no shoutbox, and barely any members are on. Is my host lying to me to get me to upgrade or is something wrong? I haven't added any new modifications within the past week or two. Here's my debug info. Let me know if you need any other info as I need this problem solved.
