[CentOS] BIND and latest update (max open files WARNING)

Hi all,

After the latest security update for bind (which came out last night), now there's a new message on syslog, (facility: daemon, severity: warning) every time you restart named:

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

After googling for a while the solution seems to be to add this to /etc/security/limits.conf:

named soft nofile 4096

...and mofity /etc/named.conf in order to add, under the options section:

files 4096;

That seems to work. Of course, you may raise the 4096 but I guess that's the default in BIND and I was good with that.

I'm not sure why this happend. Maybe before the update bind had a value of 1024 for max.sockets and now it was raised to 4096.
