SIGSEGV 11 (*) segemnetation violation

Hallo,
I run a java batch job to collect data and create Excelfile.
The job runs on OS/390 WebSphere3.5 Linux.
Since few weeks my job abends with following messages:
SIGSEGV 11 (*) segmentation violation in process 25871
SIGABRT 6 (*) abort process in process 25871
and
com.ibm.servlet.engine.srt.ClientClosedConnectionException: Client terminated connection to server before the entire response was sent. Status code: -1
     at com.ibm.servlet.engine.oselistener.nativeEntry.NativeServerConnection.write(NativeServerConnection.java(Compiled Code))
After some investigation I noticed that the volume of the created data is/can be the problem. When I decreased the amount of collected data the job ended successfully.
I have increased the heap size to "-Xms512M -Xmx1024M" but no change.
Does anybody have an idea what the problem could be?
Thanks for help in advance.
Georg

Have found the answer.
The initial java heap size and max heap size were o.k. but I have placed them in the wrong part of the command line.
This definition "-Xms256M -Xmx512M" was o.k. and sufficient.
I was looking for good documentation of heap sizes, but didn't found a good one. Just fragments here or there.
Could someone recommend a good source for documentation and description of it.
Georg

    A have installed Oracle 8.1.5 on HP_UX 11.00 - 32 bit environment
    I want to install/upgrade to Oracle 8.1.7 (64-bit)
    1. Is there any problem with this aspect ? (Oracle 8.1.7. 64-bit on HP_UX 32 bit)
    2. I need an advice regarding <new install> vs. <upgrading> ! I'm not sure if all operating system requirements are met (patch releases)
    3. What are the risk of upgrading ?

    You could try increasing the max heap size we saw alot of SIGBUS 10 crashes with sp4 until we increased this value to 1024 which happens to be the default in 6.5. Turn on garbage collection statistics with -verbose:gc if you suspect this could be the problem. The stack size should be set to about 10% the size of the (entire) registry.
    Usually however these errors tend to be code related...
    Does the crash happen at the same time everyday.

Note that there's more than one place where these are set and you may want to read the script before changing wherever appropriate. Also check to see if you indeed have that much of real memory that you allocate to the VM.
    Goodluck,
    Sharmin.

  • SIGSEGV   11*  segmentation violation

    I'm on a Sco Unixware 7.1.3 platform using
    WLS 7SP1 with SCO JDK1.3.1_06.
    This configuration is running at most of our stores, and has
    been running at this one store for 2 months with no problem until 4 days ago.
    When starting WLS, it keeps aborting and core dumping and restarting the WLS
    server after each core dump. Just finally got in my stdout log file (see below
    peice of log), but now crashes the unixware box.
    Has anyone else seen this problem or know what causes it?
    Thanks in advance.

    hi,
    i have a similar problem on my linux-server: i am runninig a java-program that parses a large xml-file (>20MB) and updates a database in background with the data of this xml-file. the programm starts without any problems, but after processing about the half file and allocating a lot of memory (about 400 to 500 MB) there occures the following error:
    SIGSEGV 11 (*) segmentation violation
    si_signo [11]: SIGSEGV: (*) segmentation violation

    the strange thing is that the program seemed to work correctly with smaller xml-files in former times. now the xml-files have permanetly grown and it seems to me that the programm has not enough handles or something to process the whole file.
    could it be a database-problem? i am using a db2 and before this problem appeared, i reduced the amount of the following database-parameters: DBHEAP, APP_CTL_HEAP_SZ, STMTHEAP, APPLHEAPSZ, MAXFILOP in order to reduce the "memory-waste". i also have tried to call the garbage collector more often so that memory is freed.
    can anybody help me please??

  • SIGSEGV   11*  segmentation violation - core dump

    Hi,
    I'm having this problem in my development machine. My machine is HP-UX 11.23.
    Previously i could install the application without any error. It just recently we install apache-tomcat, but i not sure if tomcat causes this problem. I did try to stop the tomcat process and run the installation again, but still we facing the issues.
    Kindly review the log file below. The key things that i would like to highlight is, we could not start the installation because its stop and not continuing anymore. Can somebody help me how to troubleshoot this?

    Hi,
    Thanks for your prompt reply.
    It is photoshop CS6 on the Mac.
    I re-downloaded and tried to re-install and got the same error message: serial number is REVOKED.
    This is not an installer error: I have been given an invalid serial number . This number came from my on-line accoount at Adobe.
    I paid for the purchase on 17 September 2012, and paid via PayPal as correctly shown in my Adobe accoount.
    So.... how do you get me a valid serial number?

  • Sigsegv - using a JSP/BC4J deployed application

    OC4J: developer's preview & JDev9iRC packaged version
    Info: accessing a .../xyz.jsp doesn't return,
    generates a SIGSEGV(11).
    Question urgent!!!!
    I'VE SEEN A (RECENT) POST ON THIS BOARD SPECIFICALLY DEALING WITH SIGSEGV ERROR. THE ELEPHANTWALKER MENTIONED THIS IS EITHER HARDWARE OR JVM/OS RELATED.
    WHERE DO I START LOOKING FOR A SOLUTION?
    ( - increasing stack/heap sizes
    , - move to different JVM (JDK1.3.0 ?)
    , - any known issues on AIX4.3.3 and JDK1.2.2?
    Previously I had no problems deploying and using (simple) JSPs and/or servlets in these environments. The problems seems to be related to JSP(UIX)/BC4J.

    J2RE 1.2.2 IBM build ca122-19991217

    Jan -- The developer's preview requires the 1.3.1 JVM. Please see the installation instructions at
    http://otn.oracle.com/tech/java/oc4j/htdocs/oc4j-oow-install.html
    I'm not sure if the developer's preview was tested on AIX or not. It was tested on Solaris and NT. Also, I run it on Linux
    with a 1.3.1 JVM without any significant problems.
    Please try the 1.3.1 JVM and see if that solves your issues.
    Thanks -- Jeff

    I am covering this topic in my homepage:
    http://homepages.tig.com.au/~jmsalvo/linux/oracle8i-5.html
    Granted that this page is not complete yet, revisit the page within 4 to 8 hours and it should be completed by then.
    In any case, my short answer: you do not have to use netassst. There are command line utilities to the same thing.
    You can use two tools to test a listener:
    * lsnrctl. The only problem with this is that it will use the IPC protocol and not the TCP protocol. Regardless of that, the IPC protocol requires a listner to work properly. Type help at the lsnrctl command prompt for things you can do. If you get positive reponses, then you can be sure that the IPC protocol works with the listener.
    * tnsping. This seems to use the TCP protocol. So you can run this on the same machine where 8i is installed or on another machine where 8i client software is installed (granted you have setup sqlnet.ora and tnsnames.ora).
    Hope this helps.

    Sometimes this happens after I get this error:
    com.evermind.server.http.HttpIOException: Broken pipe
    Really need some urgent help on this.
    Thanks in advance.

    There does not seem to be a bug in the application.
    If I am giving the following command which needs to check where the core dump got made
    $ file core
    core: ELF 32-bit MSB core file SPARC Version 1, from 'java'
    this is giving java as the reason for the file dump.

    Hi Yogesh,
    You've crashed the JVM. There is obviously a HUGE bug in your application.
    Fix the bug and you won't crash the JVM. The error message indicates
    that the JVM is trying to access memory it isn't allowed to access.
    In other words, I'm guessing that the JVM is trying to allocate memory
    in order to execute your java application -- but your application requires
    so much memory that the JVM is trying to grab memory that the operating
    system isn't willing to give it -- and presto,"Segment Violation".
    Now, if you want more detailed assistance in how to solve this problem,
    then I advise you to follow Jeff's suggestion, and supply more details.
    Good Luck,
    Avi.

  • Sigsegv error

    We are using Weblogic with our business logic as the server and a c++ program as
    the client. JNI is implemented to communicate between the cleint and server processes.
    The application works fine most of the times. However it fails once or twice a
    week(1 or 2 times out of 3000 runs) with SIGSEGV error and coredump. I am attaching
    the error code from the logs. Could you please let me know if you have faced a
    similar problem and the solution to it.

    disable this and verify whether it helps. If you're using type-2 native JDBC driver, you could consider replacing
    this with a type-4 all-java JDBC driver.
    You might also consider trying the JDK 1.3.x jvm.

  • Full thread dump/segmentation violation encountered in NAS4.0

    hi,
    the application is running on NAS4.0 and BillerXpert4. while accessing the database via a billerXpert api, we encounter a segmentation violation ==> full thread dump. this happens sporadically. below is an extract from the NAS log showing the error:-
    SIGSEGV 11* segmentation violation
    si_signo [11]: SIGSEGV 11* segmentation violation
    si_errno [0]:
    si_code [1]: SEGV_MAPERR [addr: 0x20302000]

    any pointers/advice as to what cld have caused this to happen?
    many thanks in advance!!

    Ah well if you're back on 1.2 then that's about as much error information as you will get.
    JDK 1.2 is way past end-of-life. There is nothing you can do here to fix this problem.
    Note: just because your application code was written for 1.2 doesn't mean it won't run on a later version of the VM. Try 1.3.1 if you don't want to jump up to 1.5 or 1.6 (but 1.3.1 will soon hit end-of-life too).
    Sorry.
