Copy VM high CPU usage !!!

We have a small-to-modest deployment of RecoverPoint.  Recently upgraded to ver 6.  2 vRPA clusters on both the prod and DR side.  Nothing special.

I don't normally pay too much attention to the copy VM's side - as production servers get replaced with newer ones, or decommissioned, sometimes the decommission procedure is not followed, so occasionally I have to manually delete the copy VM's to keep things "tidy", but that's pretty much all the regular maintenance that is performed. In other words, I (to my shame) don't look at it very much.

Today, I saw something I haven't seen before.  One of the copy VM's was reported by its vCenter as having high CPU usage.  All the other copy VM's are at 0 MHz CPU usage.  As I mentioned earlier, I don't pay too much attention to the copy VM's, so this might be normal behavior, but I thought I would ask here.  Is this normal?
