Re: web server woes!



Lookupd is the process responsible for host lookups as others have suggested. Have you tried eliminating the dynamic sites (php & mediawiki) & see if the problem continues? It may be possible that either the php app or mediawiki is trying to do a DNS lookup & thus forcing lookupd to be so heavy. A poorly coded php app that does DNS lookups & doesn't cache the results would experience the behavior you are describing. Also, you mentioned that you run your own DNS server. Is that on the same server, or a different machine? Is this machine running OS X Server or OS X Client?

Does Apache "know" its own name? Can it forward and reverse lookup its FQDN? That seems the most likely candidate for investigation.


I'm not certain about Apache, but the resolver is working. I can do reverse and forward lookups of all the IPs I use from the command line using nslookup. (Never did warm up to dig.)
