@Manoj90 In addition o @PVVK point, you need to be careful with routing relationships back on the originating processor.  During development I like to use a output port that I call End of Line or EOL1, EOL2, EOL3 as I need more in larger flows.   This is to evaluate if something goes to fail, retry, etc.  Later once I am certain the flow is working as I need, I either auto terminate these routes, or I route them out of my processor group to an Event Notification system.     It looks like this:   Using an output port to hold un needed routes during testing     If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.
