How to fix ".service: Start request repeated too quickly." on custom service?

I'm learning how to create services with systemd. I get this error: .service: Start request repeated too quickly. I can't start the service any more; it was working yesterday. What am I doing wrong? (root@Kundrum)-(11:03:19)-(~) $nano /lib/systemd/system/swatchWATCH.service 1 [Unit] 2 Description=Monitor Logfiles and send Mail reports 3 After=syslog.target network.target 4 5 [Service] 6 Type=simple 7 ExecStart=/usr/bin/swatch --config-file=/home/kristjan/.swatchrc --input-record-separator="\n \n " --tail-file=/var/log/snort/alert --daemon 8 Restart=on-failure 9 StartLimitInterval=3 10 StartLimitBurst=100 11 12 [Install] 13 WantedBy=multi-user.target StartLimitInterval and StartLimitBurst I added after trying to fix it. My system is Debian 9.8 Stretch all updates.
