Deployments created and requested from one ServiceNow instance are unexpectedly duplicating and synchronizing to a second ServiceNow instance.
Both ServiceNow instances are integrated with the same VMware Aria Automation 8.18.x environment.
Both instances share the exact same Aria Automation integration details, including the endpoint URL and identical service account authentication credentials.
The scheduled "Import Resources and CMDB" jobs, are inactive or set to false on both instances.
VMware Aria Automation 8.18.x
ServiceNow ITSM Plug-in for VCF Automation 9.x
This behavior is not caused by the default plugin synchronization jobs. Instead, this issue occurs when a event-based mechanism is enabled within the environment.
To resolve this issue and prevent unintended cross-instance resource duplication:
Review Triggers: Inspect your ServiceNow and Aria Automation environments for any active event-based mechanisms that trigger upon catalog item requests or deployment completion.
Disable the Event Mechanism: Disable or reconfigure the identified event mechanism so that it does not broadcast deployment syncs to all instances sharing the Aria Automation endpoint.
