When NetIM detects problems with database access, the service framework is automatically shut down, and Emergency level messages are displayed in the System Event Viewer. This can happen if the database is down, unreachable, or in a bad state. The service framework will also shut down if data that violates the underlying table schema is imported into the database. Some examples of this are type mismatches between data and table schema or a field overflow situation. Data problems may arise when receiving invalid or unexpected data from a third-party product or directly from a device polled by NetIM. In either case, services will shut down when the invalid data item is encountered.
