What I hear you saying is that on a system that has nothing better to do, the
primary monitoring process wakes up periodically to check on various system
aspects (cron jobs, journal rotates, etc). That sounds like working as designed
to me, not a reason to throw the proverbial baby out with the bath water. That
seems like a reason to do some tuning.
it is wasting ressources in a container running only one process -
period - what is there to discuss - in any serious setup there shou,ld
be nothing installed which is not *really* needed
