BDR Rejoin of failed node, hangs. - Mailing list pgsql-general

Good Afternoon,

I am in the process of testing out BDR and am having problems rejoining after a simulated loss of one node.   The join
hangswhile waiting to complete and there interesting errors in the logs. 


Simulation process
After creating the database on both nodes.

Shutdown postgres and reset db on node 2
   rm -rf /var/lib/postgresql/9.4/main/*
   /usr/lib/postgresql/9.4/bin/initdb -D /var/lib/postgresql/9.4/main -A trust -U postgre

Clean up node 1.
   select bdr.bdr_part_by_node_names('{node2}');
   delete from bdr.bdr_nodes where node_status='k';

When I try to re-add node2
Using the NODE 2 Create sql again, it hangs
SELECT bdr.bdr_node_join_wait_for_ready(); hangs.

The log on node2  has errors
http://pastebin.com/8ZsTe5cG
55000: System identification mismatch between connection and slot
00000: worker process: bdr db: bdrdemo (PID 12042) exited with exit code 1

The log on node1 does not have any errors.
http://pastebin.com/njVJ9WX7

Both nodes show up in select * from bdr.bdr_nodes; on node1 and node2;

Database Creation:
NODE 1
create database bdrdemo;
\connect bdrdemo
CREATE EXTENSION btree_gist;
CREATE EXTENSION bdr;
select bdr.bdr_group_create(local_node_name := 'node1', node_external_dsn := 'host=192.168.101.41 port=5432
dbname=bdrdemo');
SELECT bdr.bdr_node_join_wait_for_ready();

NODE 2
create database bdrdemo;
\connect bdrdemo
CREATE EXTENSION btree_gist;
CREATE EXTENSION bdr;
select bdr.bdr_group_join(local_node_name := 'node2', node_external_dsn := 'host=192.168.101.42 port=5432
dbname=bdrdemo',join_using_dsn := 'host=192.168.101.41 port=5432 dbname=bdrdemo'); 
SELECT bdr.bdr_node_join_wait_for_ready();
