In relation to my previous post "Bind 9.6.1: skipping zone transfer, but
why?" and Scott Hanedas post "Zone transfer failing":
I've just discovered that my Bind 9.6.1 on windows server 2008 stops
listening on tcp port 53 from time to time, UDP works fine. This gives
me errors on the slave servers like this:
01-jul-2009 10:31:14.437 general: notice: running

I tried using a dig tool which would give me an answer using UPD, but
not TCP. Restarting the ISC bind service resolved that problem.
Before the timestam of the problems, I see the following in the masters
logfile. Could the "dispatch: error: dispatch 01ED8108" error message
shed some light on what has caused named to stop listening on tcp?
(these two lines indicate that tcp is working)

(and here we see something strange)
