Unless you have 24x7x365 eyes-on-glass looking for zone transfer failures *constantly* and ready and able to *instantly* pounce on any such problems and fix them within minutes.You have been persuasive enough, I'm definitely going to raise the expire value, but now the question is: are the SERVFAIL replies a consequence of the low expire value?
most likely yeszone transerfs are retried often, but that don't help with such low expire times, the question still remains why they are failing on the same host, but that's not a bind problem
as somebody else said: you must not run both nameservers on the same host with the same internet connection, virtualization is fine but you need at least a real HA cluster and independent lines for both to minimze the possibility both nameservers are going down at the same time
i would recommend running http://www.intodns.com/ regulary for your domains http://www.intodns.com/aquilacorde.com is a horrible result!
