I did not have time to look though the code yet but was hoping for a quick answer

Does the multi line codec apply to all incoming data (IE possible to have 2 different servers mix data together. Or does the UDP Listener know the input is coming from one IP and only applies the Multiline from that incoming data?

IE

* * *

If server A sends

> date blah blah blah  
> blah blah blah

And server B sends

> yadah yahdah yadah  
> date yahdah yahday yahda

* * *

would I possible get 2 events like

> blah blah blah  
> blah blah blah  
> yadah yahdah yadah

and

> yahdah yahday yahda

* * *

or would I get 3 events

> blah blah blah  
> blah blah blah

This

> yadah yahdah yadah

and

> yahdah yahday yahda

The codec applies to all events received in the input, irrespective of where they came from.

Thanks man! I appreciate you looking. Maybe I will add this to the issues on the input or clone and try it myself.
