So the problem has nothing to do with the fact that I am not authoritative
for my reverse zone. I can run a name server with just entries in the
reverse zone files for my server without being the SOA myself?
Okay here is the output from ulimit free and uptime
alpha:~ # ulimit
unlimited
alpha:~ # uptime
 12:02pm  up 14 days, 21:41,  1 user,  load average: 1.00, 1.00, 1.00
alpha:~ # free
             total       used       free     shared    buffers     cached

I don't see anything wrong with it.
also here is what I get from rpm -V bind8
alpha:~ # rpm -V bind8

As for kernel it says package kernel is not installed I think it is
probably called something else I will check.
Thank you for your responses.
