Cause

The root cause of this behavior is internal software issue APS-39490: APS event subscriptions should be removed automatically when corresponding operation is removed in application. OA tries and retries to send event notifications regarding operations removed from application.

Resolution

Please contact Odin Technical Support Team to apply workaround for this issue.
