R2.20 30 Ubuntu 14.04 Juno multi-node setup

env.roledefs = {
    'all': [host2, host3, host4, host5, host6, host7, host8, host9],
    'cfgm': [host2, host3, host4],
    'openstack': [host2, host3, host4],
    'webui': [host3],
    'control': [host2, host3, host4],

    'collector': [host2, host3, host4],
    'database': [host2, host3, host4],
    'toragent': [host5, host6, host7, host9 ],
    'tsn': [host5, host6, host7,host9 ],
    'build': [host_build],
}

env.hostnames = {
    'all': ['nodei34', 'nodei35', 'nodei36', 'nodei37', 'nodei38', 'nodei28', 'nodei27', 'nodei30']
}

There are 128 tors each with 1k vmis and 512 lifs

For some reason today, contrail-api restarted on all the 3 config nodes around 11:45 AM .
It was later(after ~5-10 mins) seen that control-node had deleted the xmpp config from all agents/tor-agents, but never added it back
There were no xmpp flaps during this period

Logs from all 3 nodes will be in http://10.204.216.50/Docs/bugs/#
gcore of control-node and agent of nodei27(a compute-node ) will be in the same location
