Re: Firefox hangs in state 'kqread'
:Indeed, Opera hangs in kqread state just after sending a DNS lookup request,
:not especially for ad.doubleclick.net, but for every server it tries to
:connect to... whether the "Synchronous DNS" is enabled or not, BTW.

Ok, that narrows the issue down. Just yesterday my Mozilla browser
froze up for a good 5 seconds trying to lookup google.com, an address
I would not have expected to have any problems. But it has only
happened once to me in the last few days.
The question now is whether the DNS issue is due to a bug in DragonFly,
its libraries, or whether it is simply an internet glitch. I somewhat
suspect that there is a software issue somewhere, but identifying it
is going to be a difficult task at best.
In your case it could simply be the DNS server you are connecting to.
One way to mitigate the problem (if that is what it turns out to be)
is to run a caching named on your local box rather then pointing your
resolver at your ISP's DNS server. If you want to try that route take
a look at the README file in /etc/namedb on your DFly box for starter
instructions on setting up named.
