Hello @lsandinop ,

Could you provide us with a few answers to help us narrow this down:

  1. What version on Knime Executor and Knime Server are you running?
  2. Did this issue just start happening or has this always happened when you run this workflow?
  3. Do other workflows cause this issue?
  4. Could you send us the logs folder from the \logs folder?
  5. Are you running the workflow from Knime AP connected to Knime Server, or directly from the webportal?
  6. Can you also send us the Xmx settings located in your knime.ini file, which is under the folder, usually under your knime_server folder?

Once we have a bit more information, we can hopefully help fix the issue.

Thanks,
Zack
