I had a repeat issue of the situation I posted re Saturday evening - system running at 100% utilisation and had to reboot the server.
I grabbed screenshots of the offending items this time [:P]
And another 100% utilisation issue circa 23.00 BST and again at 23.16. Service_monitor using both CPU's (198%). Looks like (in the cases today/tonight) it could be triggered by a circuit failure as I could get utilisation to drop back to normal by taking the faulty circuit offline via Network/Interfaces/Interfaces, then bringing it back online.
