Association Rule Learner GC overhead limit exceded

Hi everyone,
I'm new here, and new to Knime (I'm a data mining student). For a project of mine, I have to do Market Basket Analysis over a dataset with roughly 1100000 rows, one for each item contained in a transaction.
I'm experiencing some issues with the Association Rule Learner node. I read the input file, create a collection column and then use the node. It starts to execute, but then stops and gives me the following error:
ERROR     Association Rule Learner           Execute failed: GC overhead limit exceeded
Can someone tell me what's going on here please?
What can I do to overcome this?
Thanks in advance for your help!

Did you already increase your memory?

Thanks, It worked. Or, at least I don't get the error anymore. It keeps saying the association table is empty and I still have to figure out why.
Anyway, thank you for your help! :)
