I am running Debina 2.6 servers with Bind 9 code and I get an
intermittent delay of up to 4.5 seconds the first time a given lookup
occurs.

Debian 2.6 Server:
Linux ns.unt.edu 2.6.8-2-386 #1 Tue Aug 16 12:46:35 UTC 2005 i686 GNU/Linux

Bind 9:
BIND 9.3.2

Library:
lrwxrwxrwx 1 root root 16 May 7 22:09 /usr/lib/libdns.so.16 -> libdns.so.16.0.0
-r-xr-xr-x 1 root sys 1038664 May 7 22:42 /usr/lib/libdns.so.16.0.0

I believe have tried the same code on Debian 2.4 without issue, however right now I am using 9.3.0rc2.

Debian 2.6 Server:
Linux ns0001.public.unt.edu 2.4.26-1-386 #1 Thu Jul 22 12:46:23 JST 2004 i686 GNU/Linux

Bind 9:
BIND 9.3.0rc2

Library:
lrwxrwxrwx 1 root root 25 Jan 18 2005 /usr/lib/libdns.so.11 -> /usr/lib/libdns.so.11.1.3
-r-xr-xr-x 1 root sys 1246960 Apr 7 14:25 /usr/lib/libdns.so.11.1.3

Is anyone else running a similar configuration or have a reason not to run 2.6?
