>>So far I have not seen the problem recur after I switched to using 11g. Unfortunately the problem arose again today, even when running 11g: May 19 13:24:40 ns named[398]: client 66.80.0.7#1025: error sending response: not enough free resources May 19 13:24:40 ns named[398]: client 66.80.0.7#1025: error sending response: not enough free resources >So your clients are operating in ps mode Yes, some of the clients of one of the access points (the one that's running at the coffee shop, which is where the problem arose again today) will be operating in power-save mode. (Because these clients are random 'walk in off the street' types, it's not possible in general to prevent them from using power-save mode.) > and this may be the same issue seen by one other person.

Is there any diagnostic tool that I could run - when I notice the problem occurring - that might help you in tracking down and solving this problem? Also, do you think that Joao's suggestion - copied below - is worth trying?
