Temporary Solution
cat /etc/systemd/system/lfd.service.d/override.conf
[Service]
PIDFile=/run/lfd.pid

This seems to only affect some system, not sure why but hope this information helps

We're having the exact same issue, but your temporary fix did not work. Also not impacting all of our servers.

Can provide me some log to have a look?

Looks like the issue is with CentOS 7.7 update ?
Try using,
1) # systemctl edit lfd.service
2) Add these lines
[Service]
PIDFile=/run/lfd.pid
3) systemctl daemon-reload
4) Restart lfd

Thanks,

That should resolve the issue for now. We will have this modification to the lfd service in the next release.
