Unreachable IP in allow transfer

[Hayward, Bruce]

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

123.123.123.123#53: Transfer completed: 0 messages, 0 records, 0 bytes,
224.694 secs (0 bytes/sec)

 

Thoughts?
