Thanks to all that replied. Everybody pretty much hit it on the head.
It turned out it was a DNS problem. Two weeks ago the VLAN our Blades
were in merged with another VLAN and there was an IP Address change.
The DNS server still registered both the old and new IP addesses with the
hostnames causing a conflict. I just got our hosting to set the hostnames to
the new addresses and they worked a treat.
The conflict caused really slow network transfer, NFS was horrible.
The netstat -i output has now been corrected.
Thanks again,
Will
