KNIME 5.5.0 generating JVM minidumps

KNIME Analytics Platform
1

Hi all,

after installing version 5.5.0 on our Windows Server 2019 Datacenter Edition, KNIME started generating minidumps after a Java crash.
The attached file ‘knime.log’ contains the error log generated by the batch execution of the workflow; file ‘hs_err_pid8604.log’ contains the related error log generated by the java virtual machine.

Regarding these errors I have 2 questions:

  1. What is going wrong with the new version?
  2. How can I disable the generation of minidumps in case of java crashes (e.g. -XX:-CreateCoredumpOnCrash)

Thanks in advance,
Marco

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.

Thank you @leo_woerteler,

of course I will primarily be analyzing the error cause, starting at concurrency. But, just in case, I’ll check also knime.ini.

Thanks a lot,
Marco
