Splunk DB Connect 2 is proving very difficult to get up and running:

Looks like you are running out of memory when trying to execute your query. How much data are you expecting back?
You can try increasing your heap in etc//apps//dbx//default//java.conf by adjusting the default from -Xmx256m (256MB) to a higher value.
