Hi!
The memory consumption depends on which setup you choose (basic, advanced). By default, the memory management is not set. And it will consume all the memory you have without boundaries set. Most of the micro services is a Java application. The best practice is to set the exact heap memory and allocate it at the startup. Please, set your own memory size on each microservice depends on your needs.

# .env
# Limit memory usage for each Java application
# JAVA_OPTS=-Xmx2048M -Xms2048M -Xss384k -XX:+AlwaysPreTouch

For JavaScript based (node.js) micro services like js-executor, web-ui, web-report you can use env like

NODE_OPTIONS="--max-old-space-size=200"
