Hi all,

I work with Knime and sometimes, I have a problem with the Joiner node.

Sometimes, it works for the first 60% of the execution and after, I can wait and wait, nothing progress.

I saw on other subject that it could be a memory issue. But, sometimes, it works with big data and sometimes, it doesn't work just with some hundred lines.

Do you have an idea to solve this problem ?

Try to use Cache node before Joiner on both connections.

I'm also facing the same kind of problem.

Usually the block is caused by missing values not correctly handled or something like that. This causes the increase of memory used and of the execution time.

In my case I have cleared all the data and I have also used the Cache node, but the problem still persists. I have also tried fix it with a Chunk Loop Start node, but the execution time remains extremely slow.

I didin't find a real solution for now.
