Symptoms
Symantec Scan Engine experienced an unexpected exception while attempting to scan a file. By default, Scan Engine responds by reporting an Internal Server Error to the NetApp vscan connector which prohibits access to the file. Even when Scan Engine has been configured to "Allow access and generate a log entry" in the container handling properties when a processor limit is met (or exceeded). The "Allow access and generate a log entry" is specific for container violations, and does not apply to scan errors.
