More than 100 instances of named-xfer.exe running in slave se rver .

[Fernando Nerio Fernández]

Hi Dany,
	Every single instance (of 120) of named-xfer.exe is consuming in
average 0.5 to 1% of CPU time, if a start killing some of these instances
the ones that are still running increase their use of CPU time,  keeping the
CPU usage at 100% (this happens even when just one instance is running),
when every single instance of named-xfer.exe is killed , the CPU usage drops
to 20%.

	I have found the same behaviour in another slave server that I set
up just for testing.

	Changing from AXFR to IXFR doesn´t make a difference. I am serving
around 3000 zones on this box.


If no instance of named-xfer.exe is running then the slave would not be able
to transfer any zone right?

Thanks in advance,

         Use the task manager to see whether or not they are actually doing
anything.  What process is using the most CPU? If they're doing nothing
kill them off one by one and see what happens.  How many zones are you
serving on this box? If you configure your box to use AXFR, does that make
a difference?
