    JBoss Problem with Sun 64-bit JVM

    Nick Goodman Newbie

      I have a Java 6 enterprise application that can be run in either JBoss (jboss-6.0.0.20100721-M4) or WebLogic (10.1).  When doing certain large retrieves (16,000 deep objects) using EclipseLink, JBoss, running via the Sun 64 bit JVM, crashes with a GC error (98% of time doing less than 2% of work).  What's odd, however, is that the same code works when running JBoss with the JRockit 64 bit or the Sun 32 bit JVM; moreover, with the same memory settings, the same code works on WebLogic with any of the JRockit 64 bit, Sun 32 bit, or Sun 64 bit JVM.  I would have thought that the error would be specific to the JVM and not the application server.

       

      We have played with the memory arguments to give JBoss on Sun 64 more memory, but that doesn't make any difference (even going to 4 GB of RAM for new generation still crashes).  We have also enabled the GC VM args but have not learned anything from the output during the crashes (they are 100% reproducible).  We have reproduced this on Windows Server 2003 (64 Bit) and Windows 7 (64 bit).

       

      My questions are:

       

      1) Is there some setting within JBoss that could be effecting the new generation memory space (i.e., causing it to ignore the VM settings)?

       

      2) Is the 64-bit Sun JVM widely used for application servers (our current production version has used the JRockit 64 bit VM for several years without issue, but the Sun 64 JVM beats it in several of our benchmarks).

       

       

       

      thanks,

        Nick

          What is the full GC error message?

            The stack trace is:

            • 3. Re: JBoss Problem with Sun 64-bit JVM
              Scott Marlow Master

              That is a Java core feature that can be disabled.  Try adding -XX:-UseGCOverheadLimit to your run.conf as a workaround.

               

              The feature tells you if GC is being performed very often.  IMO, It would of been better as a warning message.

              • 4. Re: JBoss Problem with Sun 64-bit JVM
                Peter Johnson Master

                Which version of the JVM are you using? ("Java 6" doesn't tell us anything, significant GC changes have gone into each point release of JDK 6.) What are you JVM options?

                 

                What operating system?

                 

                Essentially, JBoss AS doesn't do anything to control the JVM's GC algorithm; I'm not sure if that is even possible (other than setting commandl ine options). You really need to bring this to the attention of Oracle, they apparently have a bug in thier 64-bit code.

                 

                By the way, my team have used various versions (5.0.x and 6.0.x)  of the 64-bit JVM to do various performance and stress tests on Windows and Linux and never run into an issue like this.

                  The 64-bit Sun JVM I'm using is:

                  java version "1.6.0_20"
                  Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
                  Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)

                   

                  The 64-Bit JRockit JVM I'm using is:

                  java version "1.6.0_20"
                  Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
                  Oracle JRockit(R) (build R28.0.1-21-133393-1.6.0_20-20100512-2131-windows-x86_64, compiled mode)

                   

                  The 32-Bit Sun JVM I'm using is:

                  java version "1.6.0_22"
                  Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
                  Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)

                   

                  Operating Systems Used:

                  Windows 7 Professional

                  Windows Server 2003

                   

                  I believe you've misread my comments, because the code works correctly with JRockit in all environments.  The only combination that does NOT work is JBoss + Sun 64 Bit JVM.  The same code works in WebLogic with the Sun 64 Bit JVM (which makes no sense, because, as you say, JBoss probably doesn't have any control over the GC).

                    I've added that option to the startup args and now, instead of crashing, it's just hanging.  I kindof expected this because the 98/2 error (as I understand it) indicates that the GC is not able to make any progress, so a hang seems likely.  It's also worth noting that on WebLogic with this JVM or JBoss with either of the other JVMs, the query returns to our code in a short period of time.  With the 64 bit JVM and this option set, it's been running for over 4 minutes without returning (it would crash in about 40 seconds without the argument set).

                      From what I have read, setting -XX:-UseGCOverheadLimit doesn't help any because all it does is mask the problem.

                       

                      The difference in running JBoss AS and WLS is that they work entirely differently and build different sets of objects and structures to support Java EE. Therefore is is not surprising to see that the same app shows different GC patterns when run in a different app server. And of course JRockit handles GC in a completely different way.

                       

                      You could try upgrading to 1.6.0_22 to see if that helps any. But at least you are not runnign a really old version.

                       

                      You are already monitoring the GC, have you graphed the results to check for patterns?

                        What I find odd about this is that the problem occurs within an EclipseLink retrieve.  Ecilpselink is an object-relational mapping library, so I wouldn't expect it to act any differently on JBoss and WebLogic or between JVMs (other than the normal 32-64 bit differences).  I've not graphed the patterns, but i've debugged the problem a bit and it's the creation of objects that's killing the system.

                         

                        We've always assumed that many people use the Sun 64 bit JVM for JBoss (we ported to JBoss about 6 weeks ago); is this an incorrect assumption?  We've had several issues related to GC that have caused crashes (all of them involving object creation duing JDBC calls through EclipseLink).  In these cases, the behavior of WebLogic and JBoss is equivalent (they are both doing non-transactioned [supports] retrieves via a JDBC connection pool and EcilpseLink).  If the problem were in EclipseLink, I'd expect to see it occur on both environments.

                          The system actually finally did crash with this error:

                            I should add that 1.6.0_20 is the latest version for windows 64 that's posted on the download site.

                             

                            I forgot that Oracle now controlls both the Sun JVM and the JRockit JVM, so your comment about it being their issue makes more sense to me now (mea culpa).

                              it's the creation of objects

                              That is not surprising - a CG happens when an attempt is made to create an object and the young gen (actually, eden) is full. So now you are looking at the odds EclipseLink always being targetted so you have to figure out what percentage of objects are created by it as opposed to other code. And when you think about EJBs, it is mostly data objects that are being created.

                               

                              We've always assumed that many people use the Sun 64 bit JVM for JBoss  (we ported to JBoss about 6 weeks ago); is this an incorrect  assumption?

                              As a gut feeling based on forum posts I would say the ratio is about 1/3 using 64-bit, 2/3 using 32 bit. The defining choice is heap size - usually a 1.2-1.5GB heap is sufficient for most people so they stick with 32-bit.

                               

                              What are you JVM options? Looking at the GC data you posted it loks like nothing but full GCs are happening which is not good. And I must be reading the data incorrectly but it looks like the max heap size is set to something like 450MB.

                                I would look deeper into why your running out of memory.  You can following links on http://www.jboss.org/ for our consulting organization.  They could probably help you figure out what is wrong pretty quickly (if that is the kind of help you want to purchase).

                                 

                                Otherwise, you could generate a Java heap dump when you run out of memory (-XX:-HeapDumpOnOutOfMemoryError) and use the Eclipse Memory Analyzer tool (http://www.eclipse.org/mat/) to figure out what happened.

                                  Huh? I see 1.6.0_22, that's what I am running. Where are you looking?

                                    My current options are:

                                    set MEM_ARGS=-Xms1024m -Xmx2048m -XX:MaxPermSize=1024m

                                    I've also set the -Xmx down to 1GB and up to 5GB.  I've manipulated the MaxPermSize from 128m to 4GB.  The boxes I'm on have 6GB and 12GB respectively.  Our production environment reserves 10GB for our application servers.
