Problem with nmap_wrapper.nes - NMAP not scanning

[Matt C.]

I am having problems with Nessus using NMAP to port scan targets (ID:
10336). Specifically it does not appear to scan any targets. Both the
SYN scan (11219) and the TCP Connect scan (10335) work correctly. 

I am running Nessus version 2.0.12 and NMAP 3.55.
Nmap is located within my $PATH and can be called directly from the
command line without a problem.
nmap_wrapper.nes is Version: $Revision: 1.105 $
All of my scanning occurs from the nessus command line client.

As you can see below from the scan log, the nmap_wrapper.nes is
finishing almost instantaneously. 

user xxxxx starts a new scan. Target(s) : zzz.zzz.zzz.zzz, , with
max_hosts = 30 and max_checks = 25
user xxxxx : testing dns-name-ip (zzz.zzz.zzz.zzz) [12442]
user xxxxx : new KB will be saved as
/usr/local/var/nessus/users/xxxxx/kbs/dns-name-ip
user xxxxx : launching ping_host.nasl against dns-name-ip [12443]
ping_host.nasl (process 12443) finished its job in 0.010 seconds
user xxxxx : launching nmap_wrapper.nes against dns-name-ip [12444]
nmap_wrapper.nes (process 12444) finished its job in 0.019 seconds

Any help that can be provided in troubleshooting this issue would be
most appreciated.

Regards,

Matt
