JDK Crash

Hi,
If i build Apache karaf 2.2.1-SNAPSHOT against 32-bit jdk on 64-bit linux, got an error: si_signo=SIGFPE: si_errno=0, si_code=1 (FPE_INTDIV), si_addr=0xb773520b, but 64-bit jdk on 64bit, no this problem, can somebody give some suggestion? Thanks in advace!

Type :quit<Enter> to exit Vim

If i build Apache karaf...Just to make that apparent to everyone.
Normally crashes are a result of running, not building.
So in your case the compiler is crashing.
64-bit linuxLinux is a generic term. Are you running on a linux version that is specifically supported by the VM
The SIGFPE is pretty unusual. I can't recall seeing that before. I would suppose that one of the following is true.
1. There is a bug in the VM.
2. You have something unusual installed and running on your system. Maybe something wrong with patching.
3. There is a hardware failure of some sort.
The 32 bit VM (which the compiler runs with) is pretty stable. But it probably hasn't been run that much on 64 bit systems. So it is possible this is a VM bug.
I have not feeling on which of the possibilities is most likely. If you have an identical box then testing on that might be informative.

    Thanks for your help!
    Regards
    Ash

    The crash is in the library libFoundation_6_0.so in the method ZNK5viidy11IdRecordImp12getBioRecordENS8ModalityENS_8InstanceEb+0x47
    I suggest you contact the vendor for this library and get support from them.
    If the problem is repeatable, you can attach a gdb debugger and see where the fault occurs though you may need the source for this library to make any sense of it.

  • Goldengate Director admin connect crash weblogic server

    Hi
    I am running the golden gate director on 64 bit windows 2008R2. I have fired up the goldengate admin server. I have two issues.
    1) When I connect to localhost:9001/acon with weblogic for the header and left hand panel i get 403 forbidden error. right side frame shows up. I don't know what is causing that.
    2) when i connect using golden gate administration tool with admin user the weblogic crashes :( and here is the output. Looks like it goes through loop and fails. I have the schema stored in SQL 2012.
    please help on this..

    Hi,
    This crash issue usually happens when the application requires more stack size (Xss) and the default stack size of JRockit JDK is not enough. To resolve this JRockit JDK crash issue increase StackSize by adding -Xss:<value in kb> JRockit JDK argument to start script by specifying value in kb based on your application requirement.
    Mark if this helps.

  • JVM Crashes With SIGSEGV Messages

    Hi All,
    I thought that posting to this forum may be helpful as we have been trying to resolve a problem for some months that has become quite frustrating. We implemented an installation of Application Server in July last year, which was originally 9.0.3. Since then, we have been having stability problems with the OC4J application running on it, which crashes about once a week. These crashes have changed slightly in nature after application upgrades, and application server patches. We are now running the following specification:
    p650 IBM Server
    AIX 5.2 ML5
    Oracle Application Server 9.0.4.1.0
    IBM JDK 1.4.1 - version output:
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1)
    Classic VM (build 1.4.1, J2RE 1.4.1 IBM AIX build ca1411ifx-20040810 (141SR3) (JIT enabled: jitc))
    We recently symlinked in the native install of the JVM to the application server JDK directories, as we suspected a bug in the JVM was causing the problems.
    The symptoms are that the JVM process is either restarted by opmn, or that it crashes, and is uncrecoverable. We have tried increasing the heap size (which is currently 1.5GB) but this has not seemed to help. In most crashes no out of memory errors are produced, although we have seen them in the past. Usually, opmn restarts the process itself and no manual intervention is required.
    This problem could be to do with the Java code, which uses Toplink 9.0.4 to access the underlying database, however our supplier keeps proclaiming that the problem is in the IBM JDK, because their other customers aren't having the same problems on different platforms, (Windows, Linux and Solaris.)
    The application server goes down for a cold backup every morning, and most days runs through without failure.
    However, once or twice a week the JDK crashes and we have been unable to diagnose the fault.
    The output of the ipm.log at the time looks like this:

    The JVM sometimes produces thread dumps, or heap dumps, and we have added a script to do a 'kill -3' at every shutdown.
    The thread dumps seem to contain SIGSEGV messages, which is what lead the developers to suggest a JDK problem.
    We have been told that the JVM should not crash this way, regardless of what the code is like, but are not convinced that the problem lies in that area.
    Does anyone here have exprience of running Java applications on the IBM JDK an Oracle Application Server with similar problems?

    We seem to have tracked the problem down to inefficient use of large objects in the application. Excessive loading of large document objects was casuing lots of full garbage collects to be formed, which seemed to be destablising the JDK. The new release of the application stopped loading these large objects into memory except when they are actually being opened, which has kept our heap usage much more stable, and seems to have helped avert crashes.

  • Server0 gets restarted.

    Dear All,
    We are having issue with our Java on our CRM production server. When we
    try to access user management on portal the server0 gets restarted
    after some time and the window doesnt open.The problem we are getting
    is in Central instance and in application server its fine.The same
    problem we are facing in SIT and UAt server also.
    Steps for Reconstruction    
    When we login to our UI and try to access user management that wont
    open and in turn server0 gets restarted
    Thanks.
    Atul.

    Hello,
    When a server restarts, its usually an outofmemory error or in some cases a jdk crash leading to server crash.  Please check in your <j2ee engine>/work directory dev_server0 and std_server0.out files if you see errors like OutOfMemory!
    Please ensure the JVM settings are configured as per the note 723909 and the OS Specific note within.
    Please also ensure that you have heapdump settings configured as per following notes based on which OS you have:
    1004255  Sun jdk
    1267126   IBM i: How to get a heapdump which can by analyzed with MAT        
    1265455   How can you generate a system dump for analysis using MAT?        (LNX) 
    1263258 LXN / 64
    1259465 How to get a heapdump which can by analyzed with MAT          (AIX)     
    (1053495  heapdump settings on AIX)
    Thye heapdump which is .hprof file on sun jdk and on ibm its .phd/.dmp file is necessary for the analysis of the outofmemory crash if the crash is not occuring due to JVM misconfiguration but due to some memory leak.
    The heapdumps can be analyzed by MAT Tool which can be downloaded from www.ecllipse.org/mat
    Hope the above helps.

  • Error message "NoSuchMethod"

    When I try to execute my java bytecode (even the most simpliest) I get the following error message:
    Exception i thread "main" java.lang.NoSuchMethodError:main
    The Compiler does'nt complain and the programs have worked before.
    I work with Crimson editor and JDK 1.5.0_06-b05

    The problem is that I named a class "String.java"
    because I had a another class where I needed some
    methods but had to change the pathway. After that
    the Jdk "crashed". I have reinstalled the Jdk and
    have updated it to the latest version but my problems
    still occurs.You should never create a class with name String, remove that class from your project, do also the remove the compiled class files, and do a full rebuild.

  • GoldenGate Director Exception:com.goldengate.acon.ex.GGSDbAccessException

    Hi All,
    I can't run GGSCI commands correctly through Director Web GGSCI.
    When I run "stats eeast, latest" in Director Web GGSCI, I encountered this Exception:
    com.goldengate.acon.ex.GGSDbAccessException: com.goldengate.gdsc.common.ex.GDSCNetConnectException: EOF from GGSCI - unexpected end of stream.
    With this exception occurs, there comes out no result.
    When I run "start *" in Director Web GGSCI, I encountered the same exception, but the processes will be started.
    Any suggestion about this? Thank you.

The problem is that the application only works when I am using jdk 1.1.8 but not when using jdk1.2, jdk1.3 or jdk1.4. I am running the application on a Solaris 8 machine.
    I have not written the application myself but I am going to be working with it from now on. But I have today little knowledge with JNI and I have tried different approaches to solve the problem. For example I have tried to used DDD together with GDB to find out what the problem is but with no luck. When I run the application using jdk1.4 I get the following error when the JVM crashes:
    An unexpected exception has been detected in native code outside the VM.
    Unexpected Signal : 10 occurred at PC=0xFA023164

    Abort
    From this information I think that the problem should be in the native method setDebug. But I have tried to set a breakpoint at the beginning of that function in the C part but with no luck. The application crashes before it reaches that position in the C file.
    What could possibly go wrong between the setDebug function in the C part and the function call in the Java part?
    When using GDB, GDB cannot figure out what is wrong it just returns a hex address, no function name.
    I would really appreciate some help. I have tried everything that I can come up with!
    Best regards
    Lars

    I have figured out that the application fails on its first call to the native methods.
    So I have this Bitmap class that contains all the native calls and it is defined shortly as follow:
    public class Bitmap {
    static {
    System.loadLibrary("BitmapImpl");
    native void setDebug(int debuglevel, int statistics);
    There are many more native methods defined in Bitmap, but I only show the setDebug method because that is the first one that is executed and also the one that immediately fails.
    My setDebug C function is defined as follow in BitmapImpl.c
    #include <time.h>
    #include <stdio.h>
    #include <limits.h>
    #include <fcntl.h>
    #include <jni.h>
    #include <math.h>
    #include <errno.h>
    #include "Bitmap.h"
    #include "data.h"
    jint debug = 0;
    jint statistics = 1;
    JNIEXPORT void JNICALL Java_Bitmap_setDebug
    (JNIEnv *jenv, jobject jo, jint d, jint s)
    debug = d;
    statistics = s;
    My libBitmapImpl.so file is compiled using the following Makefile and using GNU gcc:
    JAVAPATH=$(JAVAINCLUDEPATH)
    LMACRO=-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DSOLARIS
    CSOURCE=BitmapImpl.c
    all:
    gcc -O3 -G $(LMACRO) -I$(JAVAPATH) -I$(JAVAPATH)/solaris \
    $(CSOURCE) -o libBitmapImpl.so
    It is still a total mystory why the application fails. I have tried it on a RedHat Linux machine and there it works fine. But not on Solaris. Only if I use the jdk1.1.8 but not a later one.
    Would really appreiciate some help!
    Best regards

  • JVM crash when used JDK 1.6

    HI ALL
    we have a stand alone program running fro every one minute on linux RHEL 4 update 4
    we upgraded our JDK to jdk 1.6 update 6
    we also have another process which is running continumouly on the system and lot of load is applied on this.
    The first process queries on db for a task and if exists processes it.
    Though this program is idle and has no task to process it has crashed.
    do we have any problem like this in JDK 1.6 update 6 when the process is idle
    the error written is as follows
    cat /tmp/hs_err_pid12381.log

    Hello,
    after some debugging with gdb, I discovered that the three crashes happen in the same instruction (mov %rcx,(%r10,%rcx,1)) and code fragment.

    0x00002aaaabb7348a:     mov    $0x2b71d36c2e30,%r10 Is it possible that it's the same bug as described in:
    [http://bugs.sun.com/view_bug.do?bug_id=6811384] [http://bugs.sun.com/view_bug.do?bug_id=6885108]
    The jdk Versions with the problem are: 1.6.0_11 and 1.6.0_16
    (We didn't test it with 1.6.0_18 as previously mentioned, sorry)

  • JDK 1.5 crashed on EM64T box running Linux AS

    Has anyone else encountered this problem?
    I'm testing the tech preview 1.5 JDK on a dual Nocona Xeon, running RedHat ES 3. The app server is actually resin (2.1.4) and not Weblogic.
    Looks like it crashed on a SIGSEV
    This is the crash dump:

When I am trying to get the default time zone using java program I still get the time zone as GMT instead of GMT+10.You do know that "Australia/Sydney" is NOT GMT+10, don't you? Sydney time uses DST, GMT does not; and therefore any timezone that is called GMT&plusmn;n will not either.
    However, that is just FYI and doesn't appear to be your issue; but without some example code we cannot help you*.

  • JVM CompilerThread Crash on compiler thread, jdk 1.4.2_15

    Hi,
    One of our customer's is seeing intermittent JVM crashes running weblogic 8.1SP6 app server on JDK 1.4.2_15, i.e. every three weeks or so.
    It crashes during executing of the compilerthread on some code in a jsp page. I've included a sample "hs_pid.log" file.
    We have not seen this in any of our testing or other production instances. I've researched and found similar bugs, but on jdk 1.5, not on jdk 1.4
    We must use jdk 1.4.2 as weblogic 8.1 does not support jdk 1.5 or later.
    Would an earlier jdk offer more stability? Also, we could switch to jrockit jvm, but would prefer to stay with sun jdk. Any other suggestions?
    thanks in advance,
    bill

    Your crash could be solved by the fix for [6579892|http://bugs.sun.com/view_bug.do?bug_id=6579892], which is reported as being in progress.
    Also of interest is [6372116|http://bugs.sun.com/view_bug.do?bug_id=6372116], which would certainly make your problem go away. Unfortunately, this was fixed in 5.0 and brought forward, but not backported to 1.4.2, so it doesn't help you. You could add a comment and vote for this one to raise the awareness of the issue.

  • VM Crash with WLS 6.1 SP2 JDK 1.3.1 on NT/MSSQL

    Has anyone seen this? If we leave the system on for overnight, WLS crashes without
    further message. Our setting is 128M, of course it will get out of memory error
    if something is asking more than that. Question is:
    who is asking for 400 MB in one shot?
    P.S. We have internal scheduler threads wake up every 5 minutes to check tasks
    thru EJBs.

    Thanks, you are right. It's a known bug in JDK 1.3.1 01 and it has been fixed in
    JDK 1.3.1 02.

  • Jdk 1.4.2.07  crashes with "stack too small" error

    http://forum.java.sun.com/thread.jspa?threadID=756468
    Cross posting this problem from the HotSpot internals forum:
    I am using jdk 1.4.2.07 and run into the following error with the VM crashing with a defunct process:"Fatal: Stack size too small. Use 'java -Xss' to increase default stack size." on Linux. Does this imply a JVM bug given that this happens only when the VM attempts to launch a large number of threads (Tomcat).
    It looks like in the absence of the Xss VM parameter, the JVM picks up the stack size based on the Linux process limits. In my case it was set to 2048k. Why would the VM crash when starting more than a threshold number of threads? My assumption is that the VM allocates the stack size to every thread. As the number of threads launched by the VM were to increase, there would be a state in which the VM would not be able to acquire more memory from the system. I have tried the latest version of the JDK 1.4.2 but it did not help.
    Any suggestions?
    Thanks

  • IMSL C library causes JVM crash through JNI in GC with JDK 1.6

    Hi Java friends,
    We use the IMSL C library (made by Visual Numerics) via JNI which picks up a C++ so on Linux. Under JDK 1.5 it works fine. Under 1.6 it crashes in the GC. I put together a very simple testcase that just calls the IMSL error options function (which sets up the library) and it causes the JVM to crash somewhere in the GC. The reason I know it's in the GC is that the crash is not immediate, it's only when the GC is active, so we wrote some test code to push the GC like this:
    log("Looping");
    long block = 10000000;
    int numBlocks = 10;
    long loops = block * numBlocks;
    for (long i = 0; i < loops; i++) {
    // Create some objects that need disposal
    String.valueOf(i);
    if (i % block == 0) {
    log("Reached " + i);
    System.gc();
    Anyone got any idea why? Crash dump follows.
    Many thanks,
    David.

    Thanks very much for your advice. Unfortunately, stepping through the code doesn't help at all. The error occurs much later after the C code has been executed, whilst running the java code (which is just creating string objects to invoke the GC). The C code that we are executing is extremely simple - it consists of Sun's JNI example coupled with a sinlge call to the IMSL error options function:
    JNIEXPORT jbyteArray JNICALL Java_ReadFile_loadFile
    (JNIEnv * env, jobject jobj, jstring name) {
    printf("%s", "Setting imsl_error_options()...\n");
    imsl_error_options( IMSL_SET_SIGNAL_TRAPPING, 0, // Disable IMSL signal trapping - necessary for MT code.
    IMSL_SET_STOP, IMSL_FATAL, 0, // Disable stopping on FATAL errors
    IMSL_SET_STOP, IMSL_FATAL_IMMEDIATE, 0, // Disable stopping on FATAL_IMMEDIATE errors
    IMSL_SET_STOP, IMSL_TERMINAL, 0, // Disable stopping on TERMINAL errors
    IMSL_SET_PRINT, IMSL_FATAL, 1, // Enable printing on FATAL errors
    IMSL_SET_PRINT, IMSL_FATAL_IMMEDIATE, 1, // Enable printing on FATAL_IMMEDIATE errors
    IMSL_SET_PRINT, IMSL_TERMINAL, 1, // Enable printing on TERMINAL errors
    IMSL_SET_PRINT, IMSL_WARNING, 1, // Enable printing on WARNING errors
    IMSL_SET_PRINT, IMSL_WARNING_IMMEDIATE, 1, // Enable printing on WARNING_IMMEDIATE errors
    IMSL_SET_PRINT, IMSL_ALERT, 1, // Enable printing on TERMINAL errors
    IMSL_SET_PRINT, IMSL_NOTE, 1, // Enable printing on TERMINAL errors
    0 );
    caddr_t m;
    jbyteArray jb;
    jboolean iscopy;
    struct stat finfo;
    const char mfile = (env)->GetStringUTFChars(
    env, name, &iscopy);
    int fd = open(mfile, O_RDONLY);
    if (fd == -1) {
    printf("Could not open %s\n", mfile);
    lstat(mfile, &finfo);
    m = mmap((caddr_t) 0, finfo.st_size,
    PROT_READ, MAP_PRIVATE, fd, 0);
    if (m == (caddr_t)-1) {
    printf("Could not mmap %s\n", mfile);
    return(0);
    jb=(*env)->NewByteArray(env, finfo.st_size);
    (*env)->SetByteArrayRegion(env, jb, 0,
    finfo.st_size, (jbyte *)m);
    close(fd);
    (*env)->ReleaseStringUTFChars(env, name, mfile);
    return (jb);
    If I remove the call to imsl_error_options then there is no adverse behaviour - the Java loop completes ok (creating 1 trillion strings in the process) and the manual call the GC works fine. With the call to imsl, the execution gets to the string creation loop (in Java, after the C has been executed) and then it dies pretty quickly (presumably after the GC kicks in to clean up some of the strings).
    Here is the java code:
    import java.util.*;
    class ReadFile {
    //Native method declaration
    native byte[] loadFile(String name);
    //Load the library
    static {
    System.loadLibrary("nativelib");
    public static void main(String args[]) {
    byte buf[];
    //Create class instance
    ReadFile mappedFile=new ReadFile();
    //Call native method to load ReadFile.java
    buf=mappedFile.loadFile("ReadFile.java");
    //Print contents of ReadFile.java
    for(int i=0;i<buf.length;i++) {
    System.out.print((char)buf);
    System.out.print("Now running the string creation loop...\n");
    long block = 100000000;
    int numBlocks = 10;
    long loops = block * numBlocks;
    for (long i = 0; i < loops; i++) {
    // Create some objects that need disposal
    String.valueOf(i);
    if (i % block == 0) {
    System.out.print("Reached " + i + "\n");
    System.out.print("Now running the GC...\n");
    System.gc();

  • Linux 32 machine crashes(shut down) wth JDK 1.6

    Hi all,
    I have JDK 1.6.0 installed on my Linux machine. Even if try javac -version on machine, It crashes.
    my machine details:
    Red Hat Enterprise Linux ES release 4 (Nahant)
    Kernel 2.6.9-5.EL on an i686
    Even if i m trying to copy the JDK from stored location,,,,the machine is crashing.
    Is there anything else which can cause the problem on machine.
    I tried on machine with JDK 1.6.04. But its showing same behaviour.But with JDk 1.5 its working fine.
    There is something wrong with machine configuration....
    Has anyone come accross such a problem??
    Thanks in advance
