Would it be possible to omit the stack trace in the warning
when a attachment cannot be found and just log the missing attachment ?
It would also be great to see the list of missing attachments in the UI or at least only the first 5 or 10 of them.
The stack traces clutter our log files with non relevant information that makes it more difficult to see real errors.
Also on our test systems which are copies of production system we usually don't have attachments and there this situation is even normal.
