UniMRCP crash without log when trying to do gdf1

[Nelson Kurniawan]

Hi,

I'm new to this group and we are setting up UniMRCP to connect to Google DialogFlow, but everytime we try to send gdf1 data from unimrcp client, the server process crashed.

Anyone know what may cause this issue?

Below is what I see from unimrcp server log when it crashed:
