If you're stuck with configuration errors, you can manually invoke the
[configuration validation](11-cli-commands.md#config-validation).
Usually Icinga 2 is a mission critical part of infrastructure and should be
online at all times. In case of a recoverable crash (e.g. OOM) you may want to
restart Icinga 2 automatically. With Systemd it is as easy as overriding some
settings of the Icinga 2 Systemd service by creating
`/etc/systemd/system/icinga2.service.d/override.conf` with the following
content:
[Service]
Restart=always
RestartSec=1
StartLimitInterval=10
StartLimitBurst=3
Run `systemctl daemon-reload && systemctl restart icinga2` to apply the changes.
Now Systemd will always try to restart Icinga 2 (except if you run
`systemctl stop icinga2`). After three failures in ten seconds it will stop
trying because you probably have a problem that requires manual intervention.
