Hi Pat,
thank you for the response.
Yes I am running R on the same machine as the NWS server. I was doing this on my Windows 2003 server with out any problem. My Linux server has 4 cores and I would like R to take advantage of them. Thank you for your help.
Cheers
Peter

Peter,
Are you running the NWS server on the same machine as the R session (ie the machine running 'twistd -y /etc/nws.tac')?
