you should contact RedHat and see if they have any options for a more
current version of rsyslog on your version.
Frankly, if you are staying with a 3.x version (when the current is 7.x)
because of RedHat support, you should be asking RedHat your support
questions. I think if you try to send a few their way you will discover
how limited their support actually is.
The other thing that you can consider doing is buying support from Adiscon
for rsyslog. This would keep it so that your entire system is still
supported by someone.

Hi Rainer
It's not that I don't want to upgrade. I would love to upgrade, but
I'm restricted to what RHN has to offer on the RHEL 5.x channel :-(
My next step is indeed to offer to put a caching server locally...
Thanx

It was brought to my attention that our centralized syslog server
(running rsyslog 3.22.1) is creating a lot of DNS queries toward one
of our DNS servers (the first one listed in /etc/resolv.conf). From a
first look at the amount of queries generated it seems that for every
message received rsyslog creates a DNS query. Is my assumption
correct?
yes
I'm only trying to get confirmation for my first (on the quick)
assumption. Not (yet) how to change (i.e. reduce) the situation.
If you do not want to upgrade to a current version, folks have solved this with
caching resolvers.
