Hi
We were chasing why we were seeing slow responses when busier (running
9.5.1-P1/Solaris 10).
In our named.conf we had an allow-transfer for IP 123.123.123.123 for
zone fredderf.com (IP/names have been changed to protect the innocent):
If the IP was not reachable we see a timeout where it tried for 224.694
secs.
I believe that this was holding up one or two processes - so the rest
had to wait
>From the xfer.log

Thoughts?
