Python ExternalProcessMemoryWatchdog error

Hi,

I use several Python Script nodes in my workflow. They were working perfectly just a week ago but now are giving me this error:

ERROR Python Script 3:673:0:1010 Execute failed: org/knime/core/data/util/memory/ExternalProcessMemoryWatchdog

If I go into the python script and only run the first few lines with “Run selected lines” (just reading the input tables and variables) it runs indefinitely. If I cancel it gives the error “There is no active python session in progress”.

My python configuration is Bundled and I had been using Anaconda in the Conda configuration. I’ve tried uninstalling conda and reinstalling miniconda, no success. I tried to remove the conda config completely and use only the bundled python, no success. I’ve tried to change the python config to manual, no success.

Any help is appreciated, thank you!
