LogRotate：非共有ポスト回転スクリプトの実行中にエラーが発生しました。

毎日のログの回転中に次のエラーが発生します。

/usr/bin/find: cannot delete ‘/var/log/tomcat/catalina.out’: Permission denied error: error running non-shared postrotate script for /var/log/tomcat/xdlogger.log of '/var/log/tomcat/*.log'

これが私のlogrotate構成です。

# cat /etc/logrotate.d/tomcat
/var/log/tomcat/*.txt
/var/log/tomcat/*.log
/var/log/tomcat/catalina.out {
    copytruncate
    daily
    dateext
    rotate 3
    compress
    missingok
    postrotate
        /usr/bin/find /var/log/tomcat/ -type f ! -name 'catalina.out' -mtime +5 -delete
    endscript
}

catalina.outとxdlogger.logの権限は次のとおりです。

# stat /var/log/tomcat/catalina.out

どこで間違っているのか教えてください。
