bind-9.3.5-P2 and socket: too many open file descriptors

[BroBind BroBind]

Hi,
Here's my  recursive clients:
[root at NAMESERVER3 ~]# rndc status
number of zones: 622
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is ON
recursive clients: 903/75000
tcp clients: 0/100
server is up and running
[root at NAMESERVER3 ~]#

And our lsof:
[root at NAMESERVER3 ~]# lsof|grep named|wc -l
1035
