Issue:
If upsteam hub tier is paired with active and passive(HA), and get queue for downstream hub is activated on both active and passive, one gets queue connection failure alert.

>> Queue 'XXX' failed to connect
Environment:
Multiple hub tier environment. A typical example is as follows.

Proxy_HUB (get) --> Customer_HUB_01 (attach queue)
Proxy_HUB_HA (get) --> Customer_HUB_01 (attach queue)

 
Cause:
attach queue is not accept connection from multiple get queues at the same time.
So if get queue (in Proxy_HUB) establish connection to attach queue (in Customer_HUB_01), get queue (in Proxy_HUB_HA) is not able to establish connection to the attach queue.
Resolution:
This behavior is a design.
Do not activate multiple get queues (pointing to the same attach queue) at the same time.
