For an IMS database feed, depending on where the error occurs, IMS Universal DB resource adapter might throw an exception, or you might get an error from the back-end IMS.
For an IMS transaction feed, the error message includes an error code with the prefix IRW and a brief description of the problem. A URL is provided for more troubleshooting information and suggested responses.
