[mwiegand]

Hi,

since recently Knime crashes whilst nothing has changed. I am running it on an AWS WorkSpace using Linux. As follows the log with the exception thrown. Hope anyone might have an idea what is happening.

I doubt that these messages are related to the problems you are seeing. I would think that those messages are printed during KNIME start (first message is saying that one of the shortcut keys are assigned twice, for different actions; the other is about one invalid update site URL, I think).

Can you elaborate more on what type of crashes you see? Is there anything executing, is the UI open?, …?

Thanks,
Bernd
