CRASH WHEN RUNNING VIA TASK SCHEDULER | JAVA 21

KNIME Analytics Platform
1

Good afternoon,

I usually schedule workflows using the Windows Task Scheduler. I recently updated to version 5.9.0, and since then KNIME has been crashing whenever a scheduled workflow starts running. Below I am providing the error log.

Note: The workflow only fails and causes a crash if KNIME is open.

Is there a solution to this problem without having to downgrade KNIME?

Merry Christmas,

Previously, I had already installed the separated batch file. The mentioned error only occurs when I have the platform open, regardless of which workflow I am editing. When it is closed, the workflow runs without any issues.

they had a change in the underlying CEF/eclipse a bit ago and now are “blocking” a workspace to be used two or more times in parallel via batch mode, too.

there is a config setting for overriding - some details are hidden somewhere in this forum (edit: thing the discussion started here: đź“Ł Out now: KNIME Analytics Platform 5.5 - #44 by Sarah_rushton )

Thanks for the reply, I see that the topic has exactly the same error as my log,
I’ll check the discussion and see if there’s a solution at the moment.
