I believe the /etc/hosts files are good on the master and the nodes. The /etc/hosts file on both the master and the nodes looks like:
# Do not remove the following line, or various programs # that require network functionality will fail. 10.0.0.100 oscar oscar_server nfs_oscar pbs_oscar 127.0.0.1 localhost localhost.oscardomain localhost 129.162.79.58 oscar oscar.geophysics.swri.edu

Hey Brandi:
Have you taken a look at your /etc/hosts file? Perhaps some entries were corrupted?
