Hello Bill

Could you specify if this happens for every zone for this single slave
or only for "large" ones?
Have you checked if this slave is allowed to do AXFR? Master's config,

You may login to slave machine and try to dig @XX.XX.XX.XX xyzzy.net AXFR

> Aug 26 14:46:09 dns2 pdns[16674]: AXFR started for 'xyzzy.net',

Take a look at master's logs as well. You may find a reason why it
closes the connection.

Hope that helps.
