Brian, your theory seems good. The problem doesn't seem to appear when I do
this.

I know Linux doesn't really have defrag utilities because it supposedly
doesn't need them (well, that's not entirely true, I know there's at least
one commercial one). So what can I do here to diagnose the exactly problem
and hopefully fix it?

have you run top to see your memory usage when you're seeing the problem?
That will tell you what's using the CPU as well as if memory is fully used
and you're swapping badly
