JVM crash upon webapp deployment to WebLogic 9.1

I have been tasked with taking a web application that has been working under WebLogic 6.1 and getting it to compile and run under WebLogic 9.1 (using Sun JDK/JRE 1.5). I resolved a few compile problems in Java sources (and commented out a few lines of JSP), made a few build script changes, and was able to compile the app. But as soon as I try to deploy it to WL 9.1 (via autodeploy), the WL process crashes with a HotSpot JVM error:
Loading services...
# An unexpected error has been detected by HotSpot Virtual Machine:
#  Internal Error (53484152454432554E54494D450E43505001A3), pid=6060, tid=5444
# Java VM: Java HotSpot(TM) Client VM (1.5.0_04-b05 mixed mode)
# An error report file with more information is saved as hs_err_pid6060.log
# If you would like to submit a bug report, please visit:
#   http://java.sun.com/webapps/bugreport/crash.jsp
#The hs_err_pid file doesn't contain any clues that I can see; the report just shows that the error occurred somewhere in the VM code. The last line of my AdminServer.log contains:
<Module poll of application appsdiriCommonsPoll_ear successfully transitioned from STATE_PREPARED to STATE_ADMIN on server AdminServer.> (that ear is the application I'm dealing with.)
In the past, working with standalone Java programs, I have found many times that a VM crash is ultimately due to native code which caused a memory violation of some kind, but there is no native code in this app. I just started trying to figure out what could be causing this -- does anyone have any insights??
Thanks for any hints you might have. I'm running this on Win XP Pro, SP 2.

I just found that the BEA JRockit "R26" build (1.5.0_04) included with WL 9.1 does NOT crash when I start with this web app deployed, whereas the latest Sun 1.5 JVM (1.5.0_12) for Windows still crashes with the same error. Weird!
Looks like this could be a Sun JVM bug after all, much to my surprise. I'm not taking this as a foregone conclusion though, so if anyone has any other hints, I'm all ears. Thanks.

    I'd been configuring this error. I appreciate any help for this. JVM crashes upon uploading transactions in my web application. Is it memory-related? Or has it something to do with my jvm version? Thank you so much.

    According to your log and error message, there was error occured in the lib
    D:\oracle\ora92\bin\oracommon9.dll. This was native code error, so you got
    JVM crashed. If you have no special requirements, you'd better use thin
    driver rather than oci driver. Thin driver maybe a little slow than oci
    dirver, but you will get more stability.

  • JVM Crash: ConcMarkSweepGC related?

    We're experiencing the following JVM crash approximately 2-5 times per day on a well traffic application server running Tomcat 5.5 under Java 1.5 (05) on Linux with a 2.4.21-37 kernel. I'm posting here because we kind of have no route to take: I can't seem to work around the crash in any way. There's a potential that UseParallelGC might fix this, but I'm unable to run the app reliably with a ParallelGC, as we have a very large cache and the Full GC's get unbelievably long (2GB heap).
    How can we find out what's going on? Is there a way to obtain a debug build so that:
    V [libjvm.so+0x4c2c53]
    V [libjvm.so+0x1bea7c]
    We're also seeing this in the standard output:
    An exception occurred on the SessionReaperDaemon[null, 2005-11-01 20:02:14.81] thread while processing (task="com.tangosol.coherence.servlet.SessionHelper$SessionReaperDaemon$IncrementalReapTask@1ba4ac8"):
    java.lang.NullPointerException

         at com.tangosol.util.Daemon$1.run(Daemon.java:63)
    Prior to the crash, but this is an impossible place for an exception:
    3070: if (iter.hasNext())
    3071: {
    3072: String sId = (String) iter.next();3073: ...
    Any help or next steps would be greatly appreciated.

    An aside: When I switch to ParallelGC, afterrunning
    for about 5-6 hours, GC times start doubling
    (approximately) in time, eventually moving upwardsof
    2 minutes per full GC.That sounds to me like you're swapping during full
    GCs. I wouldn't assume that 2 GB of physical RAM is
    sufficient to run an app with an 1800 MB heap. Have
    you done any heap profiling to determine the real
    working set of your application? When the GCs get
    this pathologically long, is there disk activity on
    the machine?Hmm.. So what should we size our heap to on a server with 2GB? The server is essentially only running the Java process. What would you consider "safe"?
    While heap profiling with jconsole, the application only utilizes 1.1GB of the heap at peaks. We want to expand that eventually as we size our caches larger.
    I don't believe there's disk activity with long GCs, but I can't confirm that 100% right now. The server is reading files from another machine, so the disks are more or less untouched while the app is running. There's heavy caching. The only reason disks would be hititng if your guess regarding the swapping turns out correct. After you suggest a safer way to calc a max heap size for our machine, I'll try again with ParallelGC and a smaller heap.
    Some points:
    - I tried increasing perm generation size. It'snot
    even close to filled (according to gc log).(As you mentioned, "old generation" instead of "perm
    generation".) What about when the full collection
    times are taking 2 minutes in duration? Is there any
    disk activity indicating swapping?Again, not positive on the disk situation -- should get an answer above to figure this out.
    - I have not tried the -client VM, will this break
    performance on a production application?The client VM does not generate as high quality
    machine code as the server VM but on the x86
    architecture many benchmark scores for the two
    compilers are comparable. I would recommend you try
    that option if only to narrow down the scope of the
    crash you're seeing.
    - I saw a bug related to a ConcMarkSweepGC crashon
    4-cpu machines opened on Oct 17th. I've testedthis
    on 4-cpu (2 proc with hyperthreading) and 2-cpu
    (hyperthreading off) -- both exhibit this issue.What bug ID is this?http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6337544
    - Are there any known issues with this collectorand
    Linux 2.4.21-37.ELsmp? Should we be using
    LD_ASSUME_KERNEL=2.2.5 or anything? For java to
    recognize this variable, do we just need itspecified
    anywhere in the environment at JVM start? How dowe
    test if it worked?No issues as far as I know, but I am not a Linux
    expert. I think in order to toggle which thread
    library is used you just need that variable exported
    in the environment when the JVM starts up. You can
    probably use pmap to see which thread library got
    loaded to verify the one you expect is present in the
    loaded objects.Trying various combinations of LD_ASSUME_KERNEL to switch threading versions has no real effect on stability there. We're seeing crashes repeatedly still.
    I'm going to attempt to deploy some machines with a new kernel as well and see if we can reproduce on those. I'll try ParallelGC again as soon as I get your recommendations on the configuration.

    elapsed time: 4500 secondsI have tried using hs_err6.pl to get some closer information, but I don't have access to the required map files, and searching in the bugdatabase didn't come up with anything.
    As far as I know this crash happened once.
    Is this a known crash, and if so: any pointers to the bugid would be very appreciated!

    Thank you.
    Going through the suggestions:
    * custom/3rd party JNI components: while the jvm args indicate a use of such components, there is actually none being used in this instance.
    * overcommit: I'm not sure whether windows has any tunables for this, but from the memory information in the hs_err file I think this is not a problem here. The JVM has Xmx1500 + Xmn128 + permsize of 128, even with generous margins this should fit well into the 4G still available physical memory on the server.
    * OS support: I'd believe that Windows 2008 SP1 is supported :)
    * OS updates: I will check with the customer whether all updates are applied, and also whether an update of the OS itself is possible.
    * hotspot/gc tuning: there are various tuning options applied, which have been determined by testing the application itself (load, functional, endurance tests), and have been found to work stable
    There is one bug we're are aware of in 6u21 which affects the application (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6938026), but without being able to decode the jvm.dll+0x1291fb address I cannot say for sure that this is the same bug.

  • JVM crashes with jdeveloper 11g and jrockit 6

    When i run my application its al going well, when i call some to show data, then all is going well,
    but when i would like to save some, then the jvm crashes, and i have no idea, i've added arguments in the jvm run configuration, etc nothing seems to work, has anybody any idea, because im getting very desperate.

    Looks like a JVM crash during classloading. Have no idea what might cause it. I suggest you try upgrading to a more recent JRockit version (google for "download jrockit" and get the latest JRMC version you can find, it includes JRockit R27.6.5). If that doesn't help, open a ticket with Oracle Support and provide the text dump and the minidump for analysis.

  • JVM Crash on Unix (Solaris)

    Hi,
    I have an application which works fine on Windows environment. If the ear prepared on Windows is deployed on Unix it works fine. But when the application is build in Unix, the application gets deployed but when accessing the application it crashes.
    I have pasted the crash details below

    I think I have localised the crash to a section of the code where there is character comparison done. If I comment out this section, it works fine. I ahve pasted below the section:
    else if (getChar() == '\'' && getOffset() < getBuffer().length())
    { // Start of a Literal - so just copy until the end of the literal
    do
    sb.append(getChar());
    setChar(getNextChar());
    while (getChar() != '\'' && getOffset() < getBuffer().length());
    sb.append(getChar()); // Append the final single quote
    setChar(getNextChar());
    After substituting " ' "for it integer value, I started getting a JVM crash with a different error id.; pasted it below

    Could you please help me to find out the cause? Also how do you make sense of the details(which I have pasted above) in the logs written at time of crash. Is there anyway to look at the core files other than dbx or gdb?
    Thanks,

  • JVM Crash on Linux Cron Restart.

    Our application is deployed in Jboss AS with MySql db under RedHat Linux.
    We scheduled a cron to restart server on everyday morning. During this time the server is not starting properly, this was not happening regularly. And the log says:

  • Error while deploying to WebLogic from Jdeveloper 11.1.1.4

    Hello,
    For some reasons, suddenly Jdeveloper gives some problems when trying to deploy an application to the internal WebLogic. It used to deploy the app without any problems in the past. I must have done something wrong and I would like to know what it is happening other than a solution to the problem.

    I did not touch any jars. They should be in their place. What I see from the project properties is that JSF 1.2 libraries are attached as before..
    Any idea? I am stuck.
    Do anyone have any idea about this matter? I really don't know where to look at.

    Please, somebody can help me to understant what append or to give me some advices?
    Thank you a lot for help.

  • JVM Crash When Using JNI and COM

    I'm trying to call a DLL compiled from VB6 source code that I do not have access to. The VB6 code simply retrieves data from a DB2 database using ADO and my client code grabs that data and marshals it to my Java code. I'm attempting to achieve this using JNI and COM (without a third-party bridge). It works 75% of the time, but the other 25% of the time, the JVM crashes with the usual Hotspot crash log containing an access violation exception. However, I don't know what in my C++ code (VC++ 8) could be causing this except for passing a "wild" pointer to the code lying underneath the COM object interface. If that is the case, I don't know how I am doing that.
    The Java code that is calling my native method is running on Tomcat 5.5.25 and just to be safe, I am not allowing multiple threads to concurrently call the method in my JNI DLL (though I realize that this will kill performance). Once I can get past this problem, I'll do the COM interfacing on a worker thread in my native code so I don't screw up CoInitialize and CoUninitialize calls in the case the same thread is concurrently executing multiple calls to my native code.
    I've noticed that in most cases, the JVM crashes during my call to the pClsAccount->OpenConnection method. However, my DLL isn't what is listed on the top of the call stack, which is why I suspect the passing of a wild pointer, though I'm just taking a guess at that. Does anyone have an idea as to what's going on ?

  • JVM crash when adding method to class

    Hello,
    I am getting some kind of problem with the virtual machine. The JVM crashes when making a class (with new). It happened when I was adding some functionality to the class, I worked my way backwards and discovered it crashes when I add any new methods, if I comment them out again everything works, adding a method by any name causes to crash.
    I went in debug to find out where it was happening, and it happens on this line:
    public PerspectiveActionToolBarHeader createPerspectiveActionToolBarHeader() {
         PerspectiveActionToolBarHeader ret = null;
         ret = new PerspectiveActionToolBarHeader(this); // << here
         return ret;
    }The PerspectiveActionToolBarHeader is the class where adding methods causes it to fail. For example, it has the method
    public Container getContainer() {
         return this;
    }and works, but if I add:
    public void anything(){} it causes a crash on the new PerspectiveActionToolBarHeader(this);
    When stepped into with the debugger it goes to the (source not found) ClassNotFoundException and eventually before the crash the (stack?) looks like this:
    Launcher$AppClassLoader(ClassLoader).loadClass(String) line: not available     
    MaldiSoftwareOptionsUIEnsemble(PerspectiveUIEnsemble).createPerspectiveActionToolBarHeader() line: 72
    and the debugger describes the class just before the crash:
    Launcher$AppClassLoader (id=44)     
    arg0     "saiman.uiobjnew.PerspectiveToolBarButton" (id=51) << has just changed
    and the log file (not sure how much to copy here!):

    I think I may have stumbled across the answer, It seems that the abstract class PerspectiveToolBar implements
    the interface with the method public Container getContainer() but does not declare it, this should be fine because the method is abstract but it crashes. When I add the method public abstract Container getContainer(); to the abstract sub-class there is no error. I'm going to try make a small compilable example to see if I can reproduce it.
    edit its actually only one of the two interface methods, and not getContainer(), but another one. If anyone is interested here is the interface:
    public interface IMassSpectrometerPassableControlContainer
         Container getContainer();
         void reloadWidgetsOnVisible(boolean visible);
    }and it works only if there is "public abstract void reloadWidgetsOnVisible(boolean visible);" in the abstract class PerspectiveToolBar implementing IMassSpectrometerPassableControlContainer.
    I tried to reproduce it, but I can't get another class to repeat the behaviour, so I don't think I can post a bug report on it. Here is my attempt anyway:
    import javax.swing.JToolBar;
    * Class     Test.java
    * Date:     7 Jun 2011
    * @author     tofuser
    public class Test extends Subclass
         public static void main(String args[])
              System.out.println("in main method");
              Test t = new Test();
              t.interfaceMethod();
         @Override
         public void interfaceMethod()
              System.out.println("interface method");
    abstract class Subclass extends JToolBar implements Interface
         private static final long serialVersionUID = 1L;
         //this line is where it breaks in my code, including it works
         //public abstract void interfaceMethod();
    interface Interface
         public abstract void interfaceMethod();
