KNIME crashes, deletes .exe file and all open workflows

Hello to the team,

I had a very strange behavior of KNIME today. During editing of a workflow, KNIME closed apruptly, without error message. After this, the knime.exe was gone from the KNIME installation directory. Also, the workflows that were open at the time were deleted from the workspace directory. And on top, the backup (export .knwf) files of the workflows were deleted from my synchronized Sharepoint folder, where I had synchronized the workflows to some 10 minutes earlier.

This has happened twice today, with different workflows.

After the first time, I replaced the knime.exe with the file from a colleague’s installation, so I was able to try again and experience the error again.

We searched for some log files that might contain any indication to the cause of this error, but found no log that had anything related to the correct time of the incident.

Is this something you want to research? If you tell me which log files in which folder you need, I would be happy to supply that.

Best regards,

Jan
