Pro gets 5 connections to an Ultrapeer; Free uses 3. So, your connections look sort of normal. When idle, only two connections are used. Look at the "time connected" to see how long each one has been connected.

btw, when running as an Ultrapeer, you'd see ~ 32 connections to other Ultrapeers, and 32 connections to leafs (~64 connections in total).

Most of those connections will be LW 4.18.8's.

Try a "What's New" search: how many results do you see there, and how quickly do they show up?
