Hi I’m running Knime on a 16GB RAM Intel I7 machine. I have a sizeable workflow. knime stops and comes up with out of heap space errors. I understand that knime keeps objects in memory which is what allows me to run each node at a time. This is with 8GB set off in the ini file for knime. I’ve managed to work around the issue by using flow variables to force knime to read the excel files one at a time. Is there a better way to do this like a generic option which stops knime from trying to read several excel files at the same time and running out of heap space. Also is there a global option or a parameter I can set to make knime not keep objects in memory when I just want to run the the workflow in production and don’t need to debug each step but prefer knime to use less memory? Any adivice or experience would be much appreciated. Thanks

Hi there @srimalj,

Then it seems you found a solution
