Another possibility is that the exception handling is flawed and it's possible for more than 1 'live' exception to exist. Check that every exception is Resumed correctly and that when re-throwing an exception the 'Preserve...' checkbox is ticked (to ensure that the same exception is thrown instead of creating another one).

Check your process for errors.   Basically this particular issue is happening in teh exception block where in my process is checking 3 times and then giving this error.    If I run manually the Process runs fine.  Fri, 27 Jul 2018 11:38:00 GMT https://community.blueprism.com/t5/Product-Forum/Getting-Issue-ERROR-Internal-Exception-A-stack-imbalance-has/m-p/44627#M1046 ParagVaishnava 2018-07-27T11:38:00Z https://community.blueprism.com/t5/Product-Forum/Getting-Issue-ERROR-Internal-Exception-A-stack-imbalance-has/m-p/44628#M1047 That error can appear when you use Set Next Stage too much - BP loses track of where the flow is going and where it has come from.
