Re: Firefox hangs in state 'kqread'
:The problem is very easy to reproduce by loading a big number of different
:sites in different tabs at the same time. I loaded every result returned
:by Google about "dragonfly bsd", and the browser froze just a few seconds
:after that.
It looks like a DNS issue. Do it again and see if just before the kq
hang it also tries to send a DNS lookup request for e.g.
ad.doubleclick.net.
Doubleclick has always been problematic for me. It got so bad that I
create a dummy master zone record for it in my named setup.
That said, there *IS* a network issue somewhere in the networking stack
which I can reproduce, and it could have something to do with the
problem too. I intend to find and fix it today.
