I have the following xml - alot many of them, in fact.

```
<log>
  <message>
    <text>T1</text>
  </message>
  <message>
    <text>T2</text>
  </message>
</log>

```

Sometimes I see that the multiline code doesn't reach the end of the file. Because of this xml filter fails citing parsing error. The size of the file was \<2MB with 50k lines.

I was able to parse bigger files without any issue. I see this sporadically.

I have set the following in multiline codec as a precaution.  
max\_lines =\> 10000000  
max\_bytes =\> '200 MiB'

Nothing seems to work. I am not able to reproduce the issue consistently in the same file also. Any ideas?
