Issue/Introduction

We are not seeing any reachability events when a device goes down.
Getting some threshold events no all
Not all events triggering 
All events not showing in CAPC 

 

Cause

These errors were seen in the Data Aggregator karaf.log

So the Data Aggregator is failing to connect pushing some events due to (Connection refused)
