Cbbackup issues 3.0.2

I’m running Couchbase Enterprise 3.0.2 on CentOS 6 and cbbackup seems to fail:

Exception in thread Thread-1:% (1144000/estimated 2391133 msgs)
Traceback (most recent call last):
File “/usr/lib64/python2.6/threading.py”, line 532, in __bootstrap_inner
File “/opt/couchbase/lib/python/pump_dcp.py”, line 432, in run
data = reader.recv(self.recv_min_bytes)
error: [Errno 104] Connection reset by peer
^Cinterrupted. ] 50.6% (1209000/estimated 2391133 msgs)

Why would this be happing. The backup script is connecting to the eth1 interface which is the private network address.

Any ideas to solve this so I can take backups?
