Seeing no data replicated with XDCR replication from cluster2 to cluster1 [cluster2 is loading data]. Node on cluster1 is down after 2-3 minutes.

Setup:

1.Setup a 2:2 node xdcr replication cluster.
2. Setup 2 unidirectional replications from cluster1-cluster2 and cluster2-cluster1
3. Load running on cluster1- replicating to cluster2 - Works as expected.
4. Remove password on bucket-2. on cluster1 and cluster2 <--- This could be an issue.
5. Start load on cluster2.
6. Cluster 2 has some memcached lost connection error, but is loading data

Errors
1. Seeing no replication on cluster1( bucket2) [ Status from replicating cluster2 shows status as "Replicating" ... We should expect this to show failed w/ reason]
2. Node(34) goes down after 2-3 minutes. - not able to get bucket2, and bucket3 ready errors on log

Able to query stats for bucket1 on node 34
Get no stats on bucket2
