Hello all,

I just noticed all my MS boxes running caching nameservers were getting 
*a lot* of bind errors! Here are the numbers on one server:

As you can see, that was worrysome!  I found out that the problems 
started with the installation of bind-9.3.6-4.P1.el5.  I tried to figure 
out what happened in that release but couldn't see anything (I should 
say I don't know much about bind).  I went to RHN and downloaded the 
previous versions:
bind-9.3.4-10.P1.el5_3.3.i386.rpm
bind-chroot-9.3.4-10.P1.el5_3.3.i386.rpm
bind-libs-9.3.4-10.P1.el5_3.3.i386.rpm
bind-utils-9.3.4-10.P1.el5_3.3.i386.rpm
caching-nameserver-9.3.4-10.P1.el5_3.3.i386.rpm

After force-installing them the error messages disappeared!

Just wanted to let you know.

Denis
