Problems scanning a range of IPs

Is there a limit to the number of IPs can be scanned per session? I am 
using nessus 2.2.2a on a redhat box, through NessusWX 1.4.5. I configure 
the range of IPs,  either IP/Mask or IPstart - IPend, multiple ranges.

For instance, currently I have

x.x.220.1 - x.x.221.238
x.x.222.1 - x.x.222.238

The scan will only run through part of the first range. I thought I was 
going crazy, checked the logs on the server. There I found the line

[Thu Jan 20 15:36:23 2005][22513] user campoe starts a new scan. Target(s) :

followed by a partial list of IPs, exactly the ones that are being 
scanned. All others do not seem to be touched at all.

Any ideas where I would 'start' troubleshooting this?
