Error decision tree learner

Hello,

I have a table with about 2.000.000 rows. I try to run the decision tree learner with that table. While the node is running I get the following messages:

WARN  KNIMEApplication$4              Potential deadlock in AWT Event Queue detected. Full thread dump will follow as debug ouput.
WARN  KNIMEApplication$3              Potential deadlock in SWT Display thread detected. Full thread dump will follow as debug ouput.
 

The node is running till 74% reached. Then the node breaks down and I get this message:

ERROR Decision Tree Learner 5:538      Execute failed: ("RuntimeException"): null

Can anybody help me? I think it is because of the big table. But are there any possibilities to process the table?

Thanks for your help!

Best,

Tash

Hello, 

now I tried to run the node with a table with 80.000 rows and instead of the Error "Execute failed: ("RuntimeException"): null" I got the Error message "Execute failed: GC overhead limit exceeded" 

What's the problem?
