Issues with BIND 9.5.0-P2

[Anatoly Pugachev]

Tested a few versions, before choose to use 9.5.1b1 on solaris 10 x86 box.
All non beta was give increased load and 'too many file descriptors' error
when i tested.

My average load in working hours on (sunfire x4100 m2) one of the our
servers with 9.5.1b1 is 2k recursive clients.

talking on this thread, i have:

# rndc status
version: 9.5.1b1
number of zones: 956
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is OFF
recursive clients: 2032/19900/20000
tcp clients: 5/100
server is up and running

# netstat -an | grep Idle | wc -l
       8
# netstat -an -P udp | wc -l
    1009
