Hi Jinmei,
I'm not sure if this is how we check for the number of sockets opened, but I'm seing over 4000. The number of recursive clients will also increase when using the P2 release (it was between 700-900 when running 9.5.1b1). 

# rndc status
version: 9.5.0-P2
number of zones: 1

xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is OFF
recursive clients: 4551/49900/50000
tcp clients: 1/100
server is up and running
