#
# Validate that stopping one replica doesn't stop Monitor IO thread till other
# managed IO threads are running.
#
# Test:
# 0. The test requires 5 servers:
# server1: group A primary
# server2: group A secondary
# server3: group B primary
# server4: group B secondary
# server5: single server
# 1. Deploy a 2 members group A in single primary mode.
# 2. Deploy a 2 members group B in single primary mode.
# 3. Configure replica to manage the asynchronous connection
# to groups A and B.
# 4. Create and start two managed channel.
# 5. Stop one of the replicas and verify Monitor IO thread is still running.
# 6. Stop the primary of group A and validate the ch2 reconnects to
# the new primary (server4).
# 7. Clean up.
