Spamassassin Restarting regulary

Few times I saw Spamassassin had stopped. On checking the logs, I see this. How to fix this?

May 21 20:05:45 server systemd[1]: Started Spamassassin daemon.
May 21 20:05:47 server systemd[1]: spamassassin.service: Succeeded.
May 21 20:05:47 server systemd[1]: spamassassin.service: Service RestartSec=100ms expired, scheduling restart.
