That looks like there's something that occasionally goes off and starts spinning, given the low memory usage and the fact that some processes using little cpu are also not swapped out.
I suspect that one of your pages has a potential infinite loop that's being triggered. Try and catch at what point the load suddenly starts rising, and check what pages were accessed around that time. They're where you should start looking. Note that you should probably focus on the access and error log lines that correspond with processes that are using excessive amounts of cpu.
