comment top command occupied high cpu usage
As you know, reboot is not a good way. Top command is a more popular tool to investigate other problem for Maintenance Engineer or Operation Engineer.

top will read /var/run/utmp file to get active user number. But this file is so big with 178M. top spends about 8s to read it that maybe occupies 57% CPU usage. Change utmp size to 10 K, top command doesn't occupy more CPU usage.
