Right scale issue - Rebalance failed

I was demoing to lower last week and I started seeing errors on rebalance and then on XDCR. The environment name is Lowes Demo 1. Also I noticed slowness in navigation.When I added a node and clicked on rebalance , I got a error message to check log for details. When I refreshed the page I could see the node added. Then I did a xdcr and when I clicked on create replication I got an error but the destination cluster was receiving the data from source.

The error message on the log screen is shown below.

Rebalance exited with reason {unexpected_exit, {'EXIT',<0.13622.2>, {noproc, {gen_server,call, [

{'janitor_agent-travel-sample', 'ns_1@ec2-35-163-104-84.us-west-2.compute.amazonaws.com'}

, {if_rebalance,<0.10921.2>, {wait_dcp_data_move, ['ns_1@ec2-54-69-70-210.us-west-2.compute.amazonaws.com', 'ns_1@ec2-34-223-202-225.us-west-2.compute.amazonaws.com'], 315}}, infinity]}}}}

I did a cb collect info and uploaded the logs in the below location. I reached out to Perry with this information and he asked me to file a bug with ns_server team.
