memory - JBoss 7.1 - Constant heap increase -


i've been tasked analyzing memory consumption issues 1 of our web apps. i'd made myself passibly familiar tools mission control , visualvm , used them resolve number of leaks, in doing came across behavior can't account.

setup

  • jboss 7.1.1 as
  • java 1.7.0_67

specifically, i've found when run jboss 7 (that is, turn off deployer , let server run) can see regular allocations (followed garbage collection) of 1mb/3 seconds or so.

on whim, took heap dumps after doing gc , once allocations had been going on. seems majority of objects i'm seeing have modules, either xerces activity (reading module xml, guess?) or objects associated moduleloader. majority of objects see have 'references' this:

my thinking (which may entirely off base) jboss scans new modules support hot deploys? thing though, use case isn't 1 ever use: new deployments involve shutting down server, dynamically scanning modules unnecessary.

i guess questions are:

  • does belief module loading have merit?

    • if so, there way jboss stop scanning?
    • if not, have suggestions else can investigate?

thanks reading!
