Queued up Events are not executing in order after integration is re-activated (Doc ID 2678938.1)

Last updated on JUNE 09, 2020

Applies to:

Oracle Integration-OIC - Version 18.2.5 and later
Oracle Integration - Version 17.4.1 and later
Information in this document applies to any platform.

Goal

OIC integration is configured to listen to the events from Engagement Cloud .
The Integration was deactivated and Event subscription was not deleted so that incoming events should be queued up for six hours according to documentation.
https://docs.oracle.com/en/cloud/paas/integration-cloud/integrations-user/deactivating-integration.html

While that Integration was deactivated, three events were generated by Engagement Cloud.

When Integration was activated the three queued up Events were not consumed immediately.
Two more events were generated by Engagement Cloud.
So at this time there are total 5 events in the queue.

It is observed these 5 events were not consumed in the order they were generated.
The three queued up Events should have been consumed before the two later updates.
Why is First-In-First-Out principle not working in this scenario ?
