Jobs Over 1 Million Records

If you have a large job (anything over 1 million records) the last step before running the job is increasing heap memory. Click the "Use Specific JVM arguments" check box and double click the "–Xmx1024mb argument". Change this to -Xmx4G to ensure proper performance when processing very large jobs over 1 million records.

This means your job is a large job and you need to increase the heap memory. Please see Jobs Over 1 Million Records for more information.
