rebalance exited ns_vbucket_mover failed to initiate_indexing

Have a 5 node cluster that was upgraded from 181 -> 202 (build 805).
After upgrade attempted to swap out orchestrator(10.3.121.69) and add in a new 202 node (10.3.3.131)

Rebalance fails with ns_vbucket_mover000 on orchestrator reporting:
<0.11037.1> exited with {noproc,
{gen_server,call,
[

{'janitor_agent-saslbucket', 'ns_1@10.3.3.131'}

,

{if_rebalance,<0.1.1>,initiate_indexing}

,
infinity]}}

On new node 202, couchdb went down and erlang crash dump was generated(attached).

Saw these errors from mccouch which may be why vbuckets couldn't be moved to this node:
