Failed flow is executing multiple times
Sometime you might see multiple error notifications for the failed flows. It would even execute all CloudFiles related actions each time. The reason for this is that Salesforce retries the failed flows automatically within 15 mins, then extending to 30 mins, then 1 hour, then 2 hours then stops retrying.
Unfortunately, there is no way to turn this behaviour off. It is discussed here on Trailblazer community
At CloudFiles, we're working to handle this better, so we avoid running CloudFiles actions multiple times in this situation. A workaround for now is to test the flows thoroughly before activating in production, so the failure chances are minimized.
