15.12.1 Reducing the number of chunks that were created during background import

If the KFAA51246-E message is output during execution of the adbimport command using the background-import facility, execute the adbmergechunk command.

By using the adbmergechunk command to merge multiple created chunks into a single chunk, you can reduce the number of chunks that were created. Once you have reduced the number of chunks, you can perform background import.
