Tomcat Excessive Memory Consumption Tanner, if you can't understand it now, how much more information do you need? Tomcat isn't using too much memory, your tool is over reporting memory. I'd like to explain why, but you're in denial that your tool is over reporting, so it's not possible to talk to you about it until you align yourself with reality. The above explains it in detail, and apparently you haven't read any of it. |

Tomcat Excessive Memory Consumption @Tanner, I tried to simplify it in a summary (in the original answer) for you. In short, stop blindly trusting your tool's output as true. |

Tomcat Excessive Memory Consumption PS, the diagram you referenced showed the internal contents of the heap. That's not the same as the overhead that lies outside of the heap. Your JVM stuffs all of those different spaces into the -Xmx(size) you specified. The only times that -Xmx is ignored is when you use a JVM that doesn't support that extension (all SUN / Oracle JVMs do, and many non-SUN / non-Oracle JVMs support that extension too, but there are a few that don't). |

Tomcat Excessive Memory Consumption That's true, however, the other items contain so little overhead in comparison to a sizeable heap that you're not in danger of watching your JVM grow to six times the size of the heap (As you are). |

Tomcat Excessive Memory Consumption You told the jvm to not allocate more heap than X; so it won't. Apart from a massive bug in the JVM that only you have noticed, how else would you explain the JVM not honoring it's configuration parameters? Call me jaded, but I think others (including myself) would be in front of Oracle's offices with pitchforks and torches if such obvious (and operational critical) functionality broke. |
