Patrick,
you say "Pelican is not tolerant of any interruption is communication
with slaves."

Does this mean that you are seeing frequent interruptions in network
connections between cluster nodes?
Have a look at the system log files - are you seeing entreies which
say ethernet interfaces are goign down?
Or NFS servers are unavailable?
If so, you really need to take a look at the network hardware.

Can you describe how many cluster nodes you have, the network cards
you have and what type of network switch,
maybe the model number?
