https://community.blueprism.com/t5/Product-Forum/Automatically-set-exception-on-session-end/m-p/71491#M24096 Hello, I have usually seen 'Automatically set exception on clean up' but never on session end. I could not find any explanation anywhere. Anyone knows the difference ?

Basically the process ends and it is still 'holding' a queue item, it does not know what to do with the item, so applies a default exception reason. Usually it is the design of the exception handling in the process that causes this. Check to see how/where your process could fail while it is holding a queue item.

Why do we have 2 exception reason in case of unhandled exceptions? Why does 'Automatically set exception on session end' even exist then? thanks Mon, 13 Nov 2017 04:05:00 GMT https://community.blueprism.com/t5/Product-Forum/Automatically-set-exception-on-session-end/m-p/71493#M24098 Carol.Ouellet 2017-11-13T04:05:00Z https://community.blueprism.com/t5/Product-Forum/Automatically-set-exception-on-session-end/m-p/71494#M24099 I've only ever known 'Automatically set exception on clean up', are you sure 'Automatically set exception on session end' isn't being applied by your process? Maybe it's a recent introduction that I'm not aware of, but regardless it means the same thing - the process design needs improvement so that queue items are handled gracefully in the event of an unexpected termination.
