EDIT: Looks like the problem was a rootkit that corrupted a bunch of low level linux commands, including top, ps, ifconfig, netstat and others. The problem was resolved by taking all web files off the server and wiping it.

A dedicated server we operate is having a strange issue. Files are not be sent complete or are showing up with garbage data. Example: http://sustainablefitness.com/images/banner_bootcamps.jpg

To make matters more confusing this corruption does NOT happen when the files are served as https, (I would post a link, but I don't have enough rep points, just add an 's' after http in the link above.)

When I throw load at the server, I get dozens of (swapd)s in top this is the only thing that really jumps out.

I can't post images but ( imgur.com / ZArSq.png ) is a screenshot of top.

I have tried a lot of stuff so far, I am willing to try anything that I can. A dedicated server we operate is having a strange issue. Files are not be sent complete or are showing up with garbage data. Example: http://sustainablefitness.com/images/banner_bootcamps.jpg
