Hi @navinjadhav,

You can set the amount of memory allocated to the server executor in /opt/knime/knime-3.7.2/knime.ini, using the -Xmx parameter. Based on your configuration, you might assign 10 GB to the executor (leaving some memory for the application server and OS-level processes).

In addition to the log files you mentioned, you can just download all log files from the WebPortal, see here:

Also see here for more information on the log files: https://docs.knime.com/2018-12/server_admin_guide/index.html#log-files

Cheers,
Roland

Hi Navin,

Just to add. The BYOL image sets sensible default values for TomEE and executor memory usage. There is a set_memory.sh script which will set the memory in the knime.ini on startup (depending on the instance size that is launched).

Best,

Jon
