I have an ISPconfig 3 install on CentOS 6.2 set up according to The Perfect Server guide. Now sometimes (once or twice a month) named goes crazy and starts eating 100% of CPU and the performace of machine drops down. I have to restart the named service and all is OK for a while. I'm using this machine as a WWW and mail server only, it doesn't act as a DNS server. Is it safe to turn named off completely? Is it used for DNS server only? Or also to resolve the addresses of outbound requests?
