I am running nessus 3.0.2 and nmap 4.03.
 
I scanned 10 hosts with both nessus and nmap.
 
Nmap identified 2 holes (HTTP and HTTPS) that Nessus "missed" on 1 of
the hosts. Several of the other 9 hosts were running these same services
and the holes WERE identified by both Nessus and Nmap.


"holes" == open ports?

It's hard to say what the cause might be without further information.
For example, which port scanner(s) are you using in your Nessus scan and
how do you have it/them configured? Have you looked at the network
traffic to see what Nessus is sending and receiving from the targets?
Are you running nmap from the same host as Nessus? ...
