hi ,  
currently am using Logstash 2.4.0 and fetching error "multiline\_codec\_max\_lines\_reached".  
my text is:

The default value is 500.  
[https://www.elastic.co/guide/en/logstash/current/plugins-codecs-multiline.html#plugins-codecs-multiline-max\_lines](https://www.elastic.co/guide/en/logstash/current/plugins-codecs-multiline.html#plugins-codecs-multiline-max_lines)

I would increase "max\_lines" in the multiline codec:

```
    codec => multiline {
        max_lines => 3000
        negate => "true"
        what => "previous"
    }
```
