DNS question

[Mark Nienberg]

I'm running a caching nameserver on my MailScanner machine.  For the 
last two days I have been seeing lots of these is /var/log/messages:

Aug  1 22:10:53 tesla named[18013]: dispatch 0x8face08: shutting down 
due to TCP receive error: 64.202.165.202#53: connection reset

The times seem to correspond to when MailScanner starts scanning a 
batch.  The IP address is always the one shown above or 68.178.211.201.

That said, named is still running and I can dig, etc.  And mail is being 
delivered.  I updated DCC, razor, and pyzor servers, so that isn't it.

Thanks for any ideas,
Mark Nienberg
