Hi @venturaz87, @iiiaaa,
These mdmp files you’re seeing are so-called Minidump files. The Java Virtual Machine (JVM) produces these files such that you may diagnose what led to the crash. To prevent your JVM from creating these Minidump files on crash, can you try putting the line -XX:-CreateMinidumpOnCrash into your knime.ini?
Best,
Marc
