Anyone here uses vaadin with springboot in production? I have a few projects with springboot running in my production server, but I now put a springboot with vaadin in same tomcat and sometimes my tomcat stop, my java will to 100% from my CPU usage. my GC takes more than 4 minutes to recover. when can’t identify with JMX any leak in code.

U can put into application.properties:

vaadin.servlet.productionMode=true
