Memory Issue Knime Version 5.3

Hi everyone,

I’ve been experiencing memory problems with KNIME 5.3 since updating. I’m running KNIME on a laptop with 8GB RAM and a 2GB graphics card.

I’m frequently getting “Out of Memory” errors, especially when working with workflows that involve Python nodes. I’ve attached my

knime.log

file for reference.

I’ve already tried modifying the

knime.ini

file (see below), but the issue persists. I’ve noticed that KNIME seems to be launching multiple Python processes, which might be contributing to the problem.

Here’s my current

knime.ini

configuration:

-vm

plugins/org.knime.binary.jre.win32.x866417.0.5.20221116/jre/bin/server/jvm.dll

-startup
