5.2 is kind of old and the 5 branch is a bit experimental,
and some subsystems are inefficient in 5.2, so that something
simple may cause an unexpected heavy load. 5.3 is better in that regard.

I'd try upgrading. Not sure if you can run a 5.3 kernel on
a 5.2 machine (things like ps are likely to break) but
you might want to try that too just to see if switching to
5.3 would fix it for you.
If it does, do upgrade the whole box, please.
