on my continuing semi-newb problem series, I have a nasty thing going on (I fear). my server is a dual opteron 8gb 600gb scsi DAM nice fast server. TOP shows 99+ idle at all times. there is very little load on it as far as i can tell. BUT - I'm seeing weird DNS responses and need some assistance - even willing to pay anyone who wants to log in and help me out. (firstname.lastname@example.org). what I'm seeing is rather odd behaviour. If I do something that needs DNS resolution (my nameserver on the server is current centos 5.1 named) - say I pull up a webpage. the first time or two I pull up an address (only some of them alas) - the browser times out. 'server not responding' etc. type messages. then I refresh again and it pops up! so obviously named is not responding fast enough (or at all)? the first 2 requests. this is not fully repeatable but I think its also why some of my customers tell me they cant send or retrive mail (most are just fine). they send me screenshots of errors like 'cant find mail server' etc. now if they try the send/receive again they will eventually get it through but its obviously something I need to resolve. any suggestions? anythign to look at??? the nameserver is ns5.cdbsystems.com if anyone wants to run tests on it and your help will be MOST appreciated (and even rewarded) thanks cdb.
