rsyslog が複数回同じモジュールをロードできない

Issue

• rsyslog は、/etc/rsyslog.conf ファイルおよび /etc/rsyslog.d/test.conf ファイルで imjournal モジュールをロードするように設定されています。

# cat /etc/rsyslog.conf
...
module(load="imjournal"         # provides access to the systemd journal
       StateFile="imjournal.state") # File to store the position in the journal
...

# cat /etc/rsyslog.d/test.conf
module(load="imjournal" ratelimit.interval="300" ratelimit.burst="30000")

• rsyslogd が、設定の確認エラーを取得します。

# rsyslogd -N1

• rsyslog デーモンは実行できますが、/etc/rsyslog.d/test.conf の設定が有効ではありません。
