Cannot fork errors

[David Henning]

Hello,

I am running Nessus on a Sun Netra T1.  It was installed using the install 
script and appeared to work correctly.  This system had been running 
previous versions of Nessus with no problems.  I am also using the latest 
version of NessusWX to connect and run the scans.  I have not changed any 
defaults for number of systems scanned in parallel, etc.

I have hundreds of "cannot fork" messages in my nessusd.messages file and 
when I run a scan against a class C address space the scan fails before 
completion.  I have included the tail of the messages file. 

Can anyone give me an idea of what to try and change or fix?
