    Java heap size problem

    Nicolas Daudin Newbie

      Hi,

      I'm using JBoss 4.0.5 and i have two applications deployed on it: the application i'm developing and JIRA.
      Since i have installed JIRA, i have had performance problems, such as gettin this in the log:

      As you can see, i set the minimal java memory size at 1024 and the max at 2048. Thinking it should be enough :)

      But the point is, i keep getting Java heap size problems (as i said earlier) and i don't know where they are coming. I don't think my apps are resource-consuming: they work perfectly locally, i can let my JBoss turn all day long without any problems, inside or outside my IDE.
      But once it came to production, i get problems.

      So, i had a look at the JMX Console, and in the Mbean {Jboss.system, type=ServerInfo}, i get the following data:

      FreeMemory java.lang.Long R 42816 MBean Attribute.
       TotalMemory java.lang.Long R 66650112 MBean Attribute.
       MaxMemory java.lang.Long R 66650112 MBean Attribute.


      So apparently from this data i understand that the actual memory of my JBoss is only 64mb... but why???
      Please help me
