we are using version 1.2.4 on Splunk 7.3.7, and we noticed our interval setting of (interval=600 / 10 mins) is not being obeyed. We can see when it does make a successful connection and pull the logs, we see at the start of the connection "HTTP connection pooling" in the logs. However, what we see subsequently are continuous connections every minute or so. We tried a splunk restart to see if this made a difference but it hasn't changed it's behaviour. So now we see connections from every 30-40 mins or longer.
