Centos 7 - High Load, low CPU, low IO wait, no processed maked as D

Question

I've got a CentOS 7 VM which seems to be stuck with quite high load (8-10). CPU usage is around 25%, there is no IO wait and there are no processes marked as D in top. I've been looking around as much as I can but these seem to be the only three causes of high load that I can find. Does anybody else know what else could be causing high load? I'm stumped!

I think those numbers are quite normal. Your CPU usage is 50%, and not 25% (don't forget the sys load - userprocesses waiting for the kernel to compute something also count as running!) ... Let's take a look at the definition of system load: link
A rough summary would be "the average number of running processes (non-idle) over time". From your top statistik, I see quite a lot of processes having a cpu load over 1%, so it is quite normal, that your system load is high.
Take note that the load numbers are not really comparable between two systems: it depends on the sampling frequency etc... So if you recently moved to a different cloud, it is totally normal that those numbers differ!
here is quite a good explanation why these numbers aren't really comparable.
