If there is a tMap component, try to use "store on disk" option. Besides, we don't have a better way to resolve this issue our component developers always commit on that.<BR />Best regards<BR />Sabrina Thu, 13 Dec 2012 02:22:09 GMT https://community.qlik.com/t5/Talend-Studio/High-CPU-usage-on-Talend-job/m-p/2283025#M57044 Anonymous 2012-12-13T02:22:09Z
