If you are receiving the tailwatchd failed email, check to make sure all the components under tailwatchd are selected; Eximstats, ChkServd , Antirelayd & cPBandwd. You can check this by
/usr/local/cpanel/libexec/tailwatchd --status
Also make sure you check the tailwatchd logs for the failure reasons:
tail /usr/local/cpanel/logs/tailwatchd_log
Then restart the Cpanel service using /etc/init.d/cpanel restart If this does not resolve your issue, you can try running a UPCP force. In addition, running a /scripts/checkperlmodules has repaired this in the past.
