> Check how much heap you have allowed jenkins to use.We're currently running with -XX:PermSize=128M -XX:MaxPermSize=512M -Xmx16384Mand the jenkins memory graph under /monitoring shows us maxing out under 12GB, and that seems excessive to me, since we only have about a dozen builds going on. Is 12-16GB there excessive and maybe indicative of a problem, or is that all standard?
That might depend on what/how you're testing. I've noticed that Maven actually uses a separate JVM. So Jenkins instance heap is one thing but you need to leave room for other processes. As seems if you have many Maven builds then all of them will allocate at least `Xms` memory. So you might want to keep `CATALINA_OPTS` low and `MAVEN_OPTS` as high as you can.
