While it's true that I'm running Centos-7 instead of Fedora, CentOS also
uses chrony as its default ntp client.
On my system "ps ax | grep -i chrony" turns up two processes, chronyd,
and the grep.
# ps ax | grep -i chrony
1113 ? S 0:02 /usr/sbin/chronyd
6982 pts/1 S+ 0:00 grep --color=auto -i chrony
chronyc does not run unless someone starts it, usually from a commandline.
it is a user tool for examining/controlling chronyd status. it shouldn't
be running all the time. Do you have a startup script somewhere that is
running it for you? If so, I'd recommend not doing that.
even if I start it from a command prompt, if I don't give it any commands
to run it consumes (as faras I can tell by watching top) zero CPU
(there's bound to be some, but it's just waiting at a command prompt,
so how much could it be?)
so it sounds like something on your system is running it and feeding it
some time-consuming commands. your task is to figure out what that is and
fix it.
good luck!

Will ntpd not address this issue?

To the extent that I am able to fetchmail from my mail servers for which I think we need
reasonably accurate system time?
I do not get why chronyc should run and create such a racket at 100% CPU.
Thanks again!
