    GC hell ?

    Andrea Vettori Newbie

      Hi,

      I'm running JBoss 4.0.5 on Redhat Linux 64. The server has two dual core processor and ten gigabyte of ram.

      I start JBoss with :

      -Xms4096m -Xmx5120m -XX:PermSize=128m -XX:MaxPermSize=256m -XX:NewSize=2048m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Xloggc:/tmp/gc.log

      I have the following problem. At server start the load is very small and the gc is called not very often, for example :

      Than after some time that I found depends on the value of NewSize parameter the GC is called a lot of times and the load reach 100% and sometimes 200%. For example :

      The server is responsive even under such load but I really want to understand why this happens and how to solve this.

      The applications makes heavy use of persistence and caches a lot of data (in web sessions) that it's probably not used very frequently but it has a limit on the cache size so I think it's not consuming all the memory.

      Any ideas ?

      How should I read the gc log ? I don't know how GC works, I tired to read the documentation but it's not very clear to me.

      Thank you

          Do you really need a 4GB heap with a 2GB young generation? Bigger is not necessarily better when it comes to Java heaps. It does look like you are freeing up 2GB of garbage every 10 seconds, that is a lot of garbage. Some code must be generating that garbage. It also looks like your working set size is around 160MB. I would try setting Xms/x to 900MB and Max/NewSize to 300MB. Or perhaps 1200M/400M. Of course, at the rate your app is generating garbage that will cause GCs to occur more often.

            Thanks.

            How can I look at what is consuming that 2GB ?
            It's not the data I cache in the session since that lives more than ten seconds... (a lot more).

            Thank you

              Unfortunately I do not know of any way of asking the JVM to state what objects it is removing as part of a GC. Actually, during a GC the JVM considers only live objects - it never even looks at dead objects that it collects.

              But you can take a heap dump - see http://java.sun.com/javase/6/docs/technotes/tools/share/jhat.html.

              If you can take a dump before a GC, that should give some idea of what is in the heap.

                I tried hat (jdk5) but it's hard to understand...

                I have a lot of char[], String and Object[]. But i see the number of classes not their size! So I can't understand who's eating the memory.

                As I suspected I have a limited number of mine classes.

                Any other hint ?

                  Sorry, but you have reached the limit of what I can do via a forum. Perhaps you should look at a commercial tool, such as JProbe, or consider paying someone to analyze your system.

                    I tried to profile the memory with various tool but I can't see anything.

                    I've tried to use jrockit and set it with 1gb newsize... The problem is still there. It's somethink like if a process on "timer" starts eating all the memory.

                    Does the default configuration of jboss have some process that starts to do something after 13 hours of boot ? Or does it exist some process that starts on a specific condition ?

                    If i restart jboss the problem is solved for some hours and then it comes back. So it can't be something related to the applications client, it must be something else!

                    It's not a memory leak because the system keeps running and the occupied memory varies (it's not always growing).

                    Any hint ?

                      First time today, after restarting the server it has started early to eat memory.

                      What can produce 1 GB of garbage in three seconds ?????

                          Is that a thread dump when it is "quite" on the server? That would be interesting, cut the LAN connection, wait a minute and then do the thread dump.

                          The SLSB passivation might be something interesting to look into. JBossCache might be involved (cluster?).

                          Also there is a thread cpu utilization tool in the JDK. Get the server in a quite state check the values, wait for 5 mins and check the values again to see which threads cause the CPU utilization.

                          In the jmx-console you'll find the ServerInfo-MBean. Invoke the listThreadCpuUtilization() operation. HTH.

                            Hi,

                            the dump is when the jvm is continually running the gc.
                            Yesterday I activated a log on the web connections. The only port reachable from the internet is the http port. In the night the server received less than 20 request.
                            But the jvm run the gc every three seconds all night long. So it can't be something that's generated by requests.

                            There is no JBossCache and I disabled the hibernate second level cache.
                            The passivation occours on some stateful session beans.

                            I'm really lost. It seems something internal to JBoss but can't understand what. Yesterday I also removed all the unneeded services but that don't helped.

                            Any other hint ?

                            Thank you

                              After experimenting I found that the problem can be an Hibernate problem.

                              Here is the post I've done

                                  I have the same issue. Starts slowly and then over time the GC gets faster and faster and eventually brings down JBOSS. With this log:

                                    For information. I'm using Hibernate within the WAR files rather than as the jboss service. Apart from that we have nothing really out of the ordinary.
