ERROR X-Aggregator Execute failed: Loop Head claims this is NOT the first iteration but the tail believes it is?!

Just a guess, the loop head is executed and all nodes in between have been configured. In order to reset the whole loop, the loop head has to be reset manually. Hope this helps?

If the X-Partitioner is green, you just right-click the node and select 'reset' from the context menu. Alternatively, you can select this node and go via the Node menu or button palette in top bar.

Thank you .

The reset did the trick and the workflow is running.

I have an aggregator at the end and it is running a while. During the running I get the following

 

WARN  TableContentModel Exception while setting new table.

 

Not sure why that is, however it still is running. Is there a way to know if he workflow is caught in an infinite loop or is that not possible.

 

I am new to knime and just don't know how long it takes. Is it possible that due to the exception, it is reparsing the data. its been running for over a half hour.

 

Thanks
