most likely yes

zone 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 regulary for your domains is a horrible result!
