You should not use the multiline filter as it has been deprecated due to having issues and serious shortcomings. Instead use the [multiline codec plugin](https://www.elastic.co/guide/en/logstash/current/plugins-codecs-multiline.html).

Perhaps Logstash is tailing the file and you need to remove the sincedb file to get it to process the file from the top?
