Re: newsrss.bbc.net.uk slightly broken?

Yes.  This is what happens when you try to re-write the query to
send a request but use the query length rather that the response
length to send the reply.

Re: unable to obtain neither an IPv4 nor an IPv6 dispatch

2014-07-18 Thread Matthew Calder
Hi Cathy,

I think you may be correct. I am running these in cloud hosted VMs. I found
that the problem is difficult to reproduce with a 2 core instance. With a 4
core instance it only happens with reload/reconfig and with 8 cores it
doesn't get past start up. From the VM's perspective, I only have 2
interfaces, lo and eth0.

Here is what shows up in the logs for BIND 9.9.5 on start.

Re: unable to obtain neither an IPv4 nor an IPv6 dispatch

2014-07-18 Thread Cathy Almond
It might have something to do with the number of CPUs that named detects
when it starts, which (by default) drives how many listening tasks it
starts per listening interface.

BIND 9.10 changed the defaults slightly, but you can also control how
many listening tasks per interface using the -U option.

Is there anything else unusual in your test set-up?   I notice you said
that you have 500 views - do you also have a large number of virtual
interfaces, each with their own listen-on?

I did an rndc dumpdb -cache and the size of the named_dump.db that
resulted is 5927042. Not all that big condidering how it is formatted.
Late last night I did a rndc flush. At that time the size of named
was 31305 pages of 8192 bytes. As of now (13 hours later) the size
is still 31305. I will see what happens.

I was asked off list for our named.conf. Here it is.
