I am having a problem with the clearsyncd deamon. It consumes a 100% of CPU and that makes the login process very slow.

Do you know how can I fix it?

What is your version of csplugin-events? You should get:
rpm -q csplugin-events
csplugin-events-1.2-3.v7.x86_64
If you don't, please bring your system up to date with a:
yum update


If it is up to date, please clear your events database with:
systemctl stop clearsync.service
rm -f /var/lib/csplugin-events/events.db
systemctl start clearsync.service

    Thank you very much. It seems that it worked. Now the CPU usage is normal.

    Thank you!
