In the forum I linked above, he had a sample workflow of how you might implement it. Additionally, you may need to wrap the workflow in a capture workflow and call on it in order to utilize the timeout settings he refers too.
However, depending on what you want, there is also the issue outlined in this forum post:
If the method outlined in the first post does not seem to work, a workaround is using KNIME business hub and just canceling the job if it takes too long and having it re execute again on cancellation.
