the not responding thing is i think because of the load
i think syslog is eating the box resources ( it is a proven fact that
syslog can do this and also BIND)
so you got the culprits i think
BIND - has no mechanism in controling the use of your resources so it will
just eat up all the resources it can.
Syslog - no mechanism either
iptraf is using Bind and syslog so nung pinatay mo na yung iptraf natapos
din yugn gamit nya ng bind and syslog so everything went back to normal :)
hehehe
and yeah i almost forgot use djbdns ( dnscache for you resolving proxy dns
server and tinydns for your authoritative content dns server) :)
