How Service calls and MQ messages are handled during quiesce as part of Pega High Availability ?

Hi Team,

During performing quiesce on a particular node, how service calls and MQ messages are handled by Pega. Do they behave any differently as when a node crashes. Can you please provide any insight on this.

Pega High Availability Guide does mention below info on how agents and listeners are handled.
The system stops non-essential agent processing for quiesce and all listeners, with the exception of message driven bean (MDB) listeners. For MDB listeners, configure the application server to ensure that no MDB invocations occur. Note: System critical agents remain active during this step.
