Seems like the majority of the entries are occuring at HH:MM:43, with some additional entries at :48 and :38.
Just curious if there is any relation to this:
These CPU-spikes happened, for my system, consequently at Uptime HH:MM:43. So, if the uptime happens to be counted from a full minute it may be very much related (but may of course still be completely unrelated), and otherwise if the uptime is counted from the actual system start chances are drastically lower (1/60 chance). I haven’t checked uptime for those spikes over reboots
