The Ubuntu Version is 18.04
Zoneminder 1.32.3
htop shows the details as per the file attached I have also included the ZM log for reference. As a Noobie some pointers would be appreciated as I have ensured the updates are applied but still seems to return to these levels even after reboot.
Its a relatively new setup (few weeks) and seems to work but just very CPU hungry in my mind for a single camera setup which is in MOCORD and at 4 fps.
All help greatly appreciated as my ears are now bleeding from the fan spin!!
