Logstash Elapsed filter 3.0.2 expired event issue


I have been using the elapsed filter on version 3.0.2.
Elapsed filter doesn't seem to generate an expired event. Is there a new configuration for the filter I'm not seeing or is this a bug?

I'm running on a windows platform.

Below is the sample code:
elapsed {
start_tag => "taskStarted"
end_tag => "taskTerminated"
unique_id_field => "priceid"
timeout => 10


Try adding the periodic_flush => true setting.
That worked for me.
