KNIME flash back

@Banksy there are several things you could try:

  • check if KNIME has enough RAM/Memory available. If you have heavy tasks I would recommend something like 75$ of your total memory while not running anything else
  • then you could try a -clean start once
  • then you could try and do a fresh install of KNIME and make sure it is not installed on a temporary or remote drive
  • then check other performance issues (official blog|my collection)

To get a detailed log I would recommend setting the Log level to debug and then deleting the log and starting KNIME again. This log you might upload here or send it to the KNIME support.
