Hi
It seems that you are meeting the same problem with this.
http://forum.java.sun.com/thread.jsp?forum=37&thread=549523&tstart=0&trange=15
You cant find the signal? Can you show the thread at the very top?
Sometimes u do need to set -XX:MaxPermSize=256M, depending on how much memory you have allocated, requirements etc.
pstack only can shows the native stack. It will be good to know what was running when it failed.

    any idea?

    Hi Jitesh
    JVM crash could be because of any code, it could be weblogic or your own application or a bug in JDK itself.
    1) You can run tools like GDB on the core file which will indicate the source of the crash.
    From the stack it looks like a Sun JDK bug
    2) Search on sun for this error code shows some known bugs. Checkout http://onesearch.sun.com/search/onesearch/index.jsp?charset=utf-8&col=developer-debugging&qt=4F530E43505002EF+01&rt=true&cs=false
    3) You can also upgrade the JVM to the latest version of 1.4.2. I believe you have 1.4.2_05

  • Hotspot JVM crash on Solaris 10: perm gen up to 99%

    Hello all,
    I got 4 JVM crashes with the same Internal Error (5349474E41545552450E43505000C0 01) reported in the Catalina output log. However I have only 1 hs_err_pid.log that is still available (the other 3 were deleted). I've noticed that the perm gen momory was up to 99% full but there was no OutOfMemory error exception. Please help. Thanks.

    Yes I am using OCI driver. But can you tell me where is the problem using OCI driver?Nope.
    If you want to spend the time then you do the following.
    1. Reduce the code to the point where you have a small example that fails
    2. Make a bug report to Oracle.
    If you want a solution, since waiting on a Oracle fix is unlikely to be something that you can do (unless you have a service contract and they state that they will fix it) then do one of the following.
    1. Use the thin driver, not the OCI one.
    2. Use a different version of the OCI driver
    3. Determine exactly where the problem occurs and find a different way to structure the code (java and SQL) so the error does not occur.
    I don't think my system is corrupted because the core is comming in customer machine as well as our test machine.
    That doesn't completely eliminate the possibility but it does make it much less likely.
    we are getting core from libjvm.so , so I think it is not the crash of oracle VM. It is the crash of SUN VM
    what do you think?The Oracle and Sun VMs are completely different applications. They are your applications so I can't tell you what you are running. The Oracle VM would, normally, be used for embedded java procs in the database itself. And if you are using OCI in that code then you are doing it wrong.

  • 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 Crashes in Native Code - JDK#1.4.2_10 for solaris-sparc

    Hi,
    We are facing irregular but quite frequent JVM crash in our Test environment. From the stacktrace it seems that JVM is crashing inside the native code. Can anyone help me in finding the cause of this problem please?

    # Please report this error at

    We are using the J2SE version 1.4.2_03 and running it on the Solaris OS 5.8. Have anybody seen this problem before? It will be great if anybody could provide some pointers to solve this problem.
    Thanks
    Ravi.

    ... Do you have any idea whether this is a known
    issue in jdk1.4.2_03 and any suggestions on how to
    check whether it is fixed in the later versions.The hs_err log that you included above, points to a rather generic
    error location (the error log dump has since been much improved
    and provides much more useful information than the dump from
    1.4.2_03 above). As such it is difficult to tell what the bug is that
    caused the crash here.
    Running with a later version might provide further clues (or it
    might be fixed already). Recall that at a refresh rate of an
    update release per each 3 months, 1.4.2_03 is already
    at least 3 years old (and perhaps more). A number of bugs
    especially in the Concurrent Mark Sweep Collector being used
    here have since been fixed.
    If testing with 1.4.2_13 is not feasible, please provide your Sun
    support contact with a core file from the incident and that might
    lead us closer to the root cause and allow us to determine if
    this may have been fixed subsequently. They may also be able to
    provide you with a test JVM binary that may lead one closer to the
    root cause.

  • 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"):

    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 Out of SWAP space

    Hello every body,
    We have a problem in a production environnement. The JVM crashes every time with the log file below.
    The application which is running don't occupate all memory and we don't understand why an outofmemory exception is raised.
    It's not probably due to an allocation inside the application because the exception should be an outofmemory exception : Java Heap space.
    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!):
    # A fatal error has been detected by the Java Runtime Environment:

    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();

  • JVM Crash: with jre 1.6.0_18 but not with 1.5.0_14

    Hello everyone,
    I got the problem that my JVM crashes when I am using the jre 1.6.0_18 but the same code runs with an jre 1.5.0_14. The code contains some JNI parts and
    is compiled with a JDK 1.5.0_14. The crash can not be reporduced within a debugger. The crash either occurs in the jvm.dll - as in the error log below - or when acessing the ntdll.dll.
    Any help is appreciated!
    Thanks in Advance!
    Here is the JVM crash report:
    # A fatal error has been detected by the Java Runtime Environment:

    I have the Java console open and after 10 seconds it closes and the applet becomes unresponsive. Usually when an applet crashes, some error messages show up in the console before it closes. That does not appear to happen in this case.
    If I load a webpage with an applet (http://java.sun.com/applets/jdk/1.4/demo/applets/Fractal/example1.html) and then move to a non-applet webpage, and have the Java console up, it stays up (alive) for about a minute before it closes. In the case of my applet it closes much faster.
    When I refresh, the second instance of the applet might be starting in the same process as the first process which is in the middle of closing (I am new to Java and JNI, so I might be using the wrong terminology). But with JRE 1.6.0.25 I was not seeing the crash on refresh. It manifested itself with the update to JRE 1.6.0.31
    I did realize the codebase was wrong. This is what I have now:

    I can reproduce the error in jdk1.5.0_03, jdk1.5.0_04 and jdk1.6.0-ea-b50. I am sure it's my program's fault, not the gc's. But as I have no knowledge of sun's JVM implementation, I don't know what may be the root cause. What error in JNI may cause the problem above?
    Hope you can help me! Thanks ahead.

    may cause this problem?
