Fault surveillance and automatic fail-over processing in broker-based messaging systems and methods

A method comprising:

• attempting, by a message broker subsystem, to deliver one or more messages intended for a recipient software application to the recipient software application during a predetermined fault interval:
• determining, by the message broker subsystem, that the recipient software application is in a fault state after failing to deliver the one or more messages to the recipient software application during the predetermined fault interval;
• automatically performing, by the message broker subsystem, a fail-over process on one or more other messages intended for the recipient software application in response to the determination that the recipient software application is in the fault state;
• continuing, by the message broker subsystem, to attempt to deliver a message selected from the one or more messages to the recipient software application during a predetermined defunct interval following the predetermined fault interval;
• determining, by the message broker subsystem, that the recipient software application is in a defunct state after failing to deliver the selected message to the recipient software application during the predetermined defunct interval;
• and
• terminating, by the message broker subsystem, a connection between the message broker subsystem and the recipient software application in response to the determination that the recipient software application is in the defunct state.

• determining, by the message broker subsystem, that the recipient software application is in a fault state after failing to deliver the one or more messages to the recipient software application during the predetermined fault interval;
• querying, by the message broker subsystem, a global service subsystem to identify an alternative recipient software application to the recipient software application;
• automatically attempting, by the message broker subsystem, to deliver one or more other messages intended for the recipient software application to the alternative recipient software application in response to the determination that the recipient software application is in the fault state:
• continuing, by the message broker subsystem, to attempt to deliver a message selected from the one or more messages to the recipient software application during a predetermined defunct interval following the predetermined fault interval;
• determining, by the message broker subsystem, that the recipient software application is in a defunct state after failing to deliver the selected message to the recipient software application during the predetermined defunct interval;
