<p class="MsoNormal"><span lang="EN-US">Hi guys,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Java process of jboss 5.1.0 eats like 500mb of RESident memory (top command) per day, which in the end fills all the swap space of the redhat linux and makes the entire system unstable.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">JBoss is configuration:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">JAVA_OPTS="-Xms128m -Xmx1024m -XX:PermSize=128M -XX:MaxPermSize=384M -Dorg.apache.el.parser.COERCE_TO_ZERO=false -Djava.awt.headless=true -Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false"<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">None of the memory visualized with jconsole(heap memory usage, non-heap memory usage, ps eden, ps survivor, ps old gen, ps code cache, ps perm gen) is growing over time, I took multiple heap dumps over time and compared.
There is no heap memory leak within the application. Also, threads are not increasing.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Never the less, the RESident memory grows and grows, so after a week usually there is no swap left anymore and jboss has to be restarted. RESident starts at 1.4gb after new start of jboss (I guess this is xmx+perm) and
increases up to 6gb before swap is used up.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The only thing I saw growing within jconsole is the “total loaded classes” which never ever gets smaller. However, the “loaded classes” stays on a constant level.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The application uses Spring, hibernate and JSF.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Do you have any ideas that can point me in the right direction?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks,<o:p></o:p></span></p>
