-25009: Failure in db communication
Explanation:
Communication between the Loader and the database takes place via the synchronous exchange of communication packages. The Loader sends a package containing the command that is to be processed to the database. This is known as a "request". While the database processes the command, the Loader waits for the package to be returned with the result. This is known as a "receive".
Errors may occur during this process if the connection from the Loader to the database is lost or if the database is no longer available.
User Action:
Use the error text to determine why the communication failed. Fix the cause or the error and restart the Loader.
