Running 4 balanced nodes of tomcat 9.0.52 in Linux. While running with production load, memory usage is slowly growing, it does not appear to really drop unless the OS/tomcat is restarted.
I did a load test locally with just login actions, did a heap dump, and MAT says: One instance of org.apache.catalina.session.StandardManager loaded by sun.misc.Launcher$AppClassLoader @ 0x9978028 occupies 59,628,760 (57.09%) bytes. The memory is accumulated in one instance of java.util.concurrent.ConcurrentHashMap$Node[], loaded by <system class loader>, which occupies 59,615,224 (57.07%) bytes. My session timeout is set to 15 minutes... I set just a name and userId in the session object in our single application running on these servers. Not sure how else to troubleshoot and/or resolve this from reaching the heap max. Are there settings to change in order to get these sessions removed from heap? Does GC occur out of the box with tomcat or do I need to define that in order for it to happen?
