Hi Gabriel,

Thanks for joining the list and sorry to hear you're having issues using
StarCluster.

This looks like a problem with portmap starting. Could you check if
portmap is running on the nodes?

Try something like:

$ /etc/init.d/portmap status

and

$ pgrep portmap -lf

I'm testing now with the ami-a19e71c8 image and c1.xlarge instances to
see if I can reproduce your issue.

Has this happened to you more than once?

~Justin
