[jboss-user] [Installation, Configuration & DEPLOYMENT] - JBoss slow after long uptime

Hi, I need help analysing a problem with my JBoss deployment. Generally the environment is stable. The problem has occurred 5 times since March and the web server handles about 250,000 - 500,000 requests per day. Problem: Sometimes the JVM suddenly gets incredibly slow. When that occurs I see that the CPU load never drops below 100% (1 CPU burning at top load). The memory consumption is higher than it should be according to the JVM setting (-Xmx2048m). I'm guessing that a garbage collector thread crashed. How can I analyse what is going wrong? config: * java version "1.6.0_04" * Java(TM) SE Runtime Environment (build 1.6.0_04-b12) * Java HotSpot(TM) 64-Bit Server VM (build 10.0-b19, mixed mode) * jboss-4.2.2.GA runs using 2GBRAM * Red Hat Enterprise Linux ES release 4 (Nahant Update 4) * hardware: 16GB Ram, 4 dual core CPUs * There is a mysql db running Thank you very much. jacques View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4173158#...
