[Beowulf] Cannot use more than two nodes on cluster

I have a small Beowulf cluster (master and 3 slaves).
I can run jobs on any single nodes.
Running on two nodes sort of works, running jobs on master and 1 slave works.
(all combos, master+slave1 or master+slave2 or master+slave3)
Running jobs on two slaves hangs.
Running jobs on master + any two slaves hangs.

Would anybody have any troubleshooting tips?
