BIND: Max open files (1024) is smaller than max sockets (4096) Error and Solution

While going though my logs I found that BIND9 on Debian version 5.x is giving a warning which read as follows:

max open files (1024) is smaller than max sockets (4096)

How do I fix this problem?

The “open files is smaller than max sockets” problem is kernel bug which is already fixed in 2.6.28. Linux kernel returns EPERM when RLIMIT_NOFILE is set to RLIM_INFINITY. To fix this issue update your Linux kernel using yum or apt-get command.
# yum update
# apt-get update
# apt-get upgrade

Reboot the server. Verify error is not reported after boot:
# tail -f /var/log/messages

See kernel bug # 461458 and 515673 for more information.
