Hi @m_monti!
Do you happen to run multiple Batch Executor processes in parallel on the same workspace? Workspaces were never meant to be shared concurrently, but the Batch Executor is missing the corresponding check: 📣 Out now: KNIME Analytics Platform 5.5 - #16 by leo_woerteler
Suppressing the dumps may be possible (e.g. by adding the JVM option you reference to the knime.ini file), but I’d much rather understand and fix the underlying problem.
