qPid connection from message processor is multi-thread or a connection pool

[myskonline2016]

I am trying to analyze how the message processor will interact with qPid Server in async mode to send analytic transaction reports.

Let's say

there are 100 concurrent requests and 10 qPid nodes.

if 80% of the requests get a valid connection and rest 20% did not ( due to any n number of reason) then what will be the status of qPid nodes from which it didnt get a connection ?

I know that the AMQ connection is a pool of 10 nodes is this case and message will be processed any active node but question is what happened to the up/down status of the AMQ pool/connection if there was some failure for some threads for some temporary period of times.

I saw that the message processor has a async thread running after every 60 sec to verify the connection to AMQ & there is a default connection timeout of 5sec to AMQ connection Target group.
