Looking at the Event Viewer I think this is exception in the Csharp code because you are attempting to modify a IEnumerable collection while its being used. Below is the exception I see when this error pops up

Unhandled exception in circuit ''.

Exception: 
System.InvalidOperationException: Collection was modified; enumeration operation may not execute.
