Hi KNIME Team,
I am using KNIME 4.0.2 with MS SQL 2016 (and their own JDBC database driver) excessively. I realize that since KNIME 4.X.X (and preassumly due to the change to the new Java stack) the Analytics Platform is becoming instable after a longer runtimes (e.g. excessive calculations or if KNIME is open for a few days with fewer calculations).
If KNIME becomes instable, I receive messages for nodes that previously worked fine. The nodes will work fine as soon as I reboot the respective computer (Windows 10).

Maybe this can be fixed in a later version of KNIME.
Thank you & best regards
