Hi @Sarah_rushton, hi @jmartinsonhr23,
as @leo_woerteler already remarked, it’s most likely due to the ‘embedded browser’ (CEF). We initialize CEF on start-up which helps to prevent problems when CEF is initialized on demand later and memory is tight. But you can turn that off by setting the system property -Dorg.knime.js.cef.skip_windowless_chromium_initialization=true. Maybe that helps as workaround (provided you don’t use view-image-generation or report-generation - which needs CEF and will initialize it when used)?
