JBoss... Memory leak

Hi All,
We are observing memory leak while running our application on JBoss 4.0.2. We attached the profiling tool - JProfiler to trace the memory leak and we found that the class[] (Proxy classes) is increasing drastically which is not getting garbage collected.
The "HeapWalker" shows that EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run() has allocated some memory which is not being freed.
The application uses MDBs extensively and the JMS server is configured to NullPersistance. We are closing all the Queue connection, session and sender properly.
What could be the possible cause for this leak?
Thanks in advance,
Nirav.

Nirav...
I am new to jboss. Our application has a memory leak on the similar issue. some UIL2 threads keep openning another copy of themselves about every minute. An example of such thread follows on the bottom of my message.
My question is this: Where do i change the connection factory type to "java:/ConnectionFactory"? I searched all of my jboss config files for "RMIConnection" and did not fing any references.
If you can offer any advice, it would be really appreciated.
thanks
julia

  • JBoss EAP 6 On JRockit - Memory Leak

    hello team.
    I have memory leak problem on jboss and jrockit.
    My Environment :
    1. OS :          
    CentOS release 6.4 (Final)
    2. JRockit :     
    java version "1.6.0_45"
         Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
         Oracle JRockit(R) (build R28.2.7-7-155314-1.6.0_45-20130329-0641-linux-x86_64, compiled mode)
    3. Application Server:
    JBoss EAP 6.2.0.GA
    4. Application
    Large EJB Application (100 and more EJB Beans (Stateless, Stateful,  MDB, Timers and so on)
    Everything works fine on older application server versions (4.3 , 4.2)
    But now I have Problem
    Of course I know that problem is new version - and i have discussion on JBoss forums.
    but guys I have question about jrockit with you:
    What is the option "Other" in memory ??

    This size increases every time - and took entire amount of RAM.

    Not sure what the 'other' is, but it is probably best shown by using an example. By using displayMap we can display a memory map of various JVM subsystems and libraries that are loaded, including third-party libraries.

    Here
    - thread is thread related (such as thread stacks)
    - int, internal use (such as pointer pages)
    - heap, chunk used by JRockit for the Java heap
    - os, mapped directly from the operating system, such as third party DLLs or shared objects
    - msp, memory space. a memory space is a native heap with a specific purpose, for example native memory allocation inside the JVM
    - gc, garbage collection related, for example live bits
    - code, compiled code
    The 'other' memory space looks to me (from the blank entries in the above print-out) like they are a memory pages to are still not used. When the JVM starts it mappes an amount of memory. To my knowledge JRockit uses mmap (mmap(2) - Linux manual page), which creates a new mapping in the virtual address space. JRockit reserves an amount of memory (Java Heap (heap where your object instances go) + its own runtime (all the others)).
    To see where the growth is in the various memory spaces, you can use 'print_memusage baseline', after which you can execute print_memusage again, for example,
    ./jrcmd 4523 print_memusage scale=M
    4523:
    Total mapped                     3896MB      +4MB (reserved=2905MB -3MB)

    - Native memory tracking            1MB           (malloced=0MB #20 +10)
    Note the additional column that prints out the difference in memory usage in relation to the baseline. You can also monitor native allocations by using trace_alloc_sites, memory allocations can then be displayed with different levels of detail using the level argument.
    ./jrcmd 4523 print_memusage trace_alloc_sites=true

    Note this is more on the JVM level, in your case in might be beneficial to investigate what is happening on the java heap. By using print_object_summary you can get insight how memory on the heap is used on a per-class basis. To get to the bottom of where the memory leak is you can use the memory-leak-detector (an example of its use can be found here Middleware Snippets: Fast, Faster, JRockit). You can also obtain a heapdump that can be analyzed by using for example MAT (see for an example here Middleware Snippets: Visualizing Class Loading). To obtain a heapdump you can run the command, for example,
    [weblogic@machine1 bin]$ ./jrcmd 4523 runsystemgc full=true fullcompact=true
    4523:
    [weblogic@machine1 bin]$ ./jrcmd 4523 hprofdump filename=/home/weblogic/dump.hprof
    4523:
    Wrote dump to /home/weblogic/dump.hprof
    Note that this first issues a full GC by using the runsystemgc command.

  • Memory Leak In DataService

    Hi All,
          I had posted this query to couple of other groups ..I am still struglling with this issue..Hope someone  will  help me out here
          I have  very basic application which uses  DataSerives over RTMP channel  to populate dataGrid , I have not used any  user defined component.
    This application has got LOAD data and Remove data  Button just to simulate the actual application
    What happens , when I click on LOAD data , It  loads the data from server(JBOSS) then I Remove all the data and force the GC to run
    If I continuously keep loading and removing the  data ,  memory goes up every time and after some times It reaches to threshold and  finally crashes the Browser.
    In actual application as soon as user logs in a dedicated DS destination is created..
        private function createDestination(destName:String):void{
                 var remoteService:RemoteObject = new RemoteObject("DestinationManager");
                 remoteService.addEventListener(ResultEvent.RESULT, resultHandler,false,0,true);
                 var operation:AbstractOperation = remoteService.getOperation("createDestination");
                 operation.send(destName);
                 var cs:ChannelSet = new ChannelSet();
                 var rtmpChannel:RTMPChannel = ServerConfig.getChannel("my-rtmp") as  RTMPChannel;
                 cs.addChannel(rtmpChannel);
                 tradeService = new DataService() ;
                 tradeService.destination=destName;
                 tradeService.channelSet = cs;  
    Now when user hits on Load data button to load the trade data ...
       public function loadData():void
             var remoteService:RemoteObject  = new RemoteObject("filterRemoteVO");
             var operation:AbstractOperation = remoteService.getOperation("loadData");
             tradeService.fill(tradeCollection);
             operation.send(rowData.text ,GUIID);
             tradeList.dataProvider = tradeCollection;
    Remove Data  hit I clean all the resource and released collection :-
          public  function  removeAll():void{
             if(tradeList.dataProvider){
                  tradeCollection.source = new Array();
                  tradeList.dataProvider.source = new Array();
                  tradeList.dataProvider = null;
                tradeService.release();
               tradeService.releaseCollection(tradeCollection);
              tradeService.channelSet.disconnectAll();
              tradeService.disconnect();
               tradeService.logout();
               System.gc();
    Except these 3 function I don't have any code which could cause memory leak.
    I m using
    LCDS 2.5
    Flex 3.0
    JBoss4.2
    Please see the mxml file below   , If  possible please have a look at it , I might  not be using dataSerice API correctly.
    I have been trying to solve this leak for last two week , I really need help from you guys.
    My client has already evaluating other contemporary technology because of this memory issue.
    I have also created scalled down war file which can be deployed on any  java application server.
    Any help will greatly be appreciated

    Dam

    Hi Natasha,
    Sorry for late reply.
          I tried your suggestion but It did not help to release memory. Actully,this app contains only one event handler which is for remote method call , I dont think this could cause any memory leak.
    Profiling session reveals that It is the issue of DataService class.I dont know How do I convince  Adobe to investigate this issue.
    Regards,
    Dharmendra

  • Memory leak within FOProcessor class

    Hi all,
    I'm trying to use the XML Publisher API (5.6.2 and 5.6.3) to generate PDF documents from XSL templates and XML data in a J2EE environment (Jboss 4.0.5) with Struts but a memory leak occurs.
    It seems not to be a multithreading issue because the leak is there even if the PDF documents are generated one by one.
    I made many tests to isolate the leak and I have simplified my code as much as possible: it seems to happen within the FOProcessor class.
    One of the tests generates 4,500 PDF documents (one at a time) from an XML file (3 KB) and an XSL file (74 KB with blanks). Nothing else is done with the Jboss server during this test. The XSL file was created before the test from a RTF file with XML Publisher. The memory leak is around 70 KB for each PDF document (around 300 MB for the whole test).
    As you can see below from the heap histogram (taken at end of test after a full garbage collection) it seems that the XSL and XML elements/attributes are not released (and thus never garbage collected).
    Did I miss something or is there an actual problem with the XML/XSL parsing within the XML Publisher API?
    Thanks for your help.

  • Memory Leak in Linux OS

    Using JNI1.2 for C++ and JAVA communication. And the Java application is a multithread application and monitoring JBoss application server using JMX. In each 5 minute interval the C++ application is invoking a method of java class and for each method call its creating a thread and retrieving the value from JBoss.
    the Code in run method of thread is as follows
    Object obj = context.lookup( "ejb/mgmt/MEJB" );
              ManagementHome home = (ManagementHome) PortableRemoteObject.narrow(obj,ManagementHome.class);
              server = home.create();
    //after that am retrieving the value
    But for each iteration the memory is increasing by 2MB of JVM . Its looks like a memory leak in JVM. The JVM version am using is 1.4.2.6.
    Could any one suggest me what may be the problem. THis problem is not occuring in Window OS.
    Thanks in advance.

    The JVM version am using is 1.4.2.6.Give it a try with 1.4.2_08.

  • JSF (RI) app hot-deploy memory leak

    I have a standard JSF (RI) based web app that appears to be working just fine in terms of functionality. However, I believe that there is a memory leak associated with the sort of frequent hot-deploy cycles that are typical during a normal development cycle. I have been monitoring the app via the jvmstat 3.0 tools and have witnessed NO memory growth in the young or old generation areas - regardless of useage pattern. All of the growth seems to happen in the perm area of memory and be directly coincidental with the occurence of a deploy. Eventually, continued hot-deply cycles will result in an OutOfMemory error on the container - please note that continued and extensive use of the app WITHOUT the aforementioned hot-deploys does NOT result in the OutOfMemory error.
    From my research so far, I have discovered the following thread:
    http://forum.hibernate.org/viewtopic.php?t=935948&postdays=0&postorder=asc&start=75
    It refers to a similar problem with hiberate (which I am NOT using) as well as a commons-logging and several others. From the looks of it, I strongly suspect that there may be an issue with JSF when it's implementation is bundled inside the WEB-INF/lib dir - i.e. inside the specific web app's ClassLoader.
    Based on the above, I have implemented a SessionContextListener that invokes the org.apache.commons.logging.LogFactory.release() inside the contextDestroyed( ServletContextEvent e ) method. This does appear to free up some perm memory but there is still large growth that appears to be directly related to the FacesServlet initialization (navigation handlers, etc). I looked into calling the FacesContext.release() method which seems to have purpose similar to that of the LogFactory.release() method. However, at the time of the contextDestroyed() invocation, FacesContext.getCurrentInstance() always returns null, so I do not ever have an opportunity to invoke the release method that I am aware of. If my suspicions are correct, than I would likely be able to avoid this problem entirely by simply placing the JSF implementation jars in the conatiner's shared lib dir - instead of bundling it inside WEB-INF/lib. However, this is not an option for this container as multiple web apps (which require the flexibility to use differing JSF implementations and versions - i.e. RI vs MyFaces, etc) will run on this container.
    I don't believe it is at all related to the problem at hand, but my container is JBoss 4.0.2.
    Any and all assistance and suggestion will be greatly appreciated! Has anyone else seen this sort of behavior? Are there any work arounds or corrective actions?
    TIA

    Has anyone else run into this? I'd greatly appreciate any assistance as I cannot seem to resolve this hot-deploy related leak.

  • How to determine memory leaks?

    I tried in XCODE, the RUN/ Start with Performance TOol / and tried out the various options. I was running my app and looking to see if it would report increasing memory use but it seemed to be looking at my total system (i was running under the simulator). In general what is the recommended procedure for determining memory leaks, which tool to use, and what tracing can i use?
    How does one look at the retain count of an object? are there system routines that have knonw leaks?

    You took the right path. Once instruments comes up select the Leaks tool. Turn off automatic leak detection. In your app, start off at some known state, do something, and come back to the known state and check for leaks. For instance start off in a view, do something that brings up another view then come back to the original view and check for leaks. Leaks will show you if you leaked. Since you took a very deterministic path then checked it should be straight forward to go to the code and find / fix the leaks. Leaks shows you where the code where the leak was generated.

  • Memory leak in JSpinner implementation (maybe others?)

    Hi,
    I am developing an application using Java and Swing, and have run into some problems with memory leaks. After examining the source code and making an example program (provided below), I can only come to the conclusion that there is a bug in the implementation of JSpinner in Sun Java 1.6.0_03.
    If one uses a custom model with the JSpinner, it attaches itself as a listener to the model. However, it never removes the listening connection, even if the model is changed. This causes the JSpinner to be kept in memory as long as the model exists, even if all other references to the component have been removed.
    An example program is available at http://eddie.dy.fi/~sampo/ModelTest.java . It is a simple swing program that has the JSpinner and two buttons, the first of which writes to stdout the listeners of the original model and the second changes the spinner model to a newly-created model. A sample output is below:
    Running on 1.6.0_03 from Sun Microsystems Inc.
    Listeners before connecting to JSpinner:
      Model value is 0, 0 listeners connected:
    Listeners after connecting to JSpinner:
      Model value is 0, 2 listeners connected:
      1: interface javax.swing.event.ChangeListener
      2: javax.swing.JSpinner$ModelListener@9971ad
    Listeners now:
      Model value is 8, 2 listeners connected:
      1: interface javax.swing.event.ChangeListener
      2: javax.swing.JSpinner$ModelListener@9971ad
    Changing spinner model.
    Listeners now:
      Model value is 8, 2 listeners connected:
      1: interface javax.swing.event.ChangeListener
      2: javax.swing.JSpinner$ModelListener@9971adThis shows that even though the model of the JSpinner has been changed, it still listens to the original model. I haven't looked at other components whether they retain connections to the old models as well.
    In my case, I have an adaptor-model which provides a SpinnerModel interface to the actual data. The adaptor is implemented so that it listens to the underlying model only when it itself is being listened to. If the JComponents using the model were to remove the listening connections, it, too, would be automatically garbage-collected. However, since JSpinner does not remove the connections, the adaptor also continues to listen to the underlying model, and neither can be garbage-collected.
    All in all, the listener-connections seem to be a very easy place to make memory leaks in Java and especially in Swing. However, as I see it, it would be a simple matter to make everything work automatically with one simple rule: Listen to the models only when necessary.
    If a component is hidden (or alternatively has no contact to a parent JFrame or equivalent), it does not need to listen to the model and should remove the connections. When the component is again set visible (or connected to a frame) it can re-add the connections and re-read the current model values just as it does when initializing the component. Similarly, any adaptor-models should listen to the underlying model only when it itself is being listened to.
    If the components were implemented in this way, one could simply remove a component from the frame and throw it away, and automatically any listener-connections will be removed and it can be garbage-collected. Similarly any adaptor-models are collected when they are no longer in use.
    Changing the API implementation in this way would not require any changes to applications, as the only thing that changes are the listener-connections. Currently used separate connection-removing methods should still work, though they would be unnecessary any more. The API would look exactly the same from the view of an application programmer, only that she would not need to care about remnant listening connections. (As far as I can tell, the current API specification would allow the API to be implemented as described above, but it should of course require it to be implemented in such a way.)
    Am I missing something, or is there some valid reason why the API is not implemented like this?
    PS. I'm new to these forums, so if there is a better place to post these reports, please tell me. Thanks.

    Another cognition: It's the following code, that causes the memory to be accumulated:
    obj = m_orb.resolve_initial_references("NameService");
    ctx = NamingContextExtHelper.narrow(obj);For the first 4 calls to this code the memory usage of the nameservice is unchanged. From the 5th to the 8th call, it's increased by approx. 10KB per call. And thenceforward (beginning with the 9th call) it's increasing by approx. 10MB.
    What's going wrong here?

    2009 8 core Mac Pro w/ 24 GB of RAM, ATI Radeon 4870, and a SeriTek PCIe eSATA card (card only has drives connected when running a manual drive clone).  When running Toast 10 or Parallels 9, my RAM will fill up (I use a program called Menu Meters to monitor stuff).  This machine worked just fine under OS 10.9 and earlier - no issues like this at all.  ClamXAV will also completely fill the RAM up (the meter will be full green, instead of part green, then mostly grey when Toast or Parallels fills it up).  I have to use Terminal to purge it so that the machine is usable.
    The other thing that happens is that sometimes when the computer wakes up or I am in the middle of doing something, the mouse will still move, but the dock will not pop open and the left button the mouse doesn't respond.  The right button will open the right click menu, but will not respond normally at all.  I have tried a different Magic Mouse, but the problem is the same.
    I thought that it may be a problem with the factory RAM and the Kingston RAM not playing nicely together.  So I ran it with just the factory 8 GB and then ran it with the Kingston 16 GB - the problem persists no matter which RAM is installed.  All of the RAM also passes the memory tests in Rember and TechTool.
    So, I need to find out if someone thinks that maybe the bluetooth module may be going bad causing the mouse issues.  I also need to find out what is causing the memory leaks.  I followed the steps that someone gave on this site to boot into safe mode, repair permissions, reset PRAM, then reset SMC (or the other way around - I did it like they said to).  It did nothing to fix the problem.
    I need some guidance here.  As I stated early on, the machine worked perfectly with OS 10.9.  I have WAY too much software that I use, so doing a completely fresh install is out of the question - I don't have time to reload everything.  This problem is annoying and I know that I am not the only one having these issues.  Any input will be greatly appreciated.  Thanks in advance.

    Here is the EtreCheck report:
    Problem description:
    Memory leaks when using Toast 10 or Parallels 9.  Mouse also become unresponsive (it will move, but left button does not work and dock will not pop open - mouse problem happens independent of the RAM being filled up - different mouse was tried with same result).

  • T61 with memory leak on XP for driver battc.sys

    Hi
    I have an issue with XP where the battc.sys module that is part of Windows XP and responsible for the kernel side of monitoring the battery status. This module continually leaks memory until I have no more kernel paged resources left and programs start to fail on my laptop.
    I raised a support case for this with Microsoft and after some investigation and upgrading to the latest T61 power drivers that were released a few days ago on the Lenovo site, MS support told me it is a fault of the T61 and that I would need to disable Microsoft APCI support to stop this memory leak from occuring and to take the issue up with Lenovo.
    I have used the verifier tool to confirm that it is the Windows XP SP3 battc.sys memory module leaking.
    I am running the latest T61 drivers and fully patch with MS drivers on SP3.
    As MS have told me it is the fault of the T61 I am posting this issue here.
    Thanks
    Stephen

    It is memory available to the kernelwhich itself does not show under a process in task manager as far as I am aware (unles it is taken account as part of the system process).
    The best way to measure the available kernel memory space available is by using sysinternals procexp.
    You need to download procexp and also install the windows debugging tools from Microsoft. Then in procexp set the "Options > Configure Symbols : Debughlp.dll path" to the new debughlp.dll installed with your debu tools and set the symbols path to srv*c:\Symbols*http://msdl.microsoft.com/download/symbols
    Then you can choose in procexp "View > System Information" and see the used and total paged and non-paged kernel memory space.
    poolmon helps monitor all the symbols that are taking up this memory and verifier lets you drill down to the exact module and the changes in memory for a module that is occuring.
    Here are two really good links on it
    http://blogs.msdn.com/ntdebugging/archive/2006/12/18/Understanding-Pool-Consumption-and-Event-ID_3A0...
    http://blogs.msdn.com/ntdebugging/archive/2008/05/08/tracking-down-mmst-paged-pool-usage.aspx
    In my poolmon i notice that Mmst and battc are taking alot of memory after my computer has been running for some time. Mmst being high is normal but battc should not continually be growing as it is which is why I raised the case to MS but they want verification it is not a Lenovo issue.

  • How do I report a major memory leak problem with Firefox 3.6.10 in WinXP?

    After I installed Firefox 3.6.9 on a WinXP desktop, I occasionally had minor memory leak problems, reflected by getting "out of virtual memory" messages. I upgraded to 3.6.10 when notified that it was available and that it supposedly fixed stability problems. Ever since then, whenever I use Firefox, it starts out quick as a flash, but very rapidly slows down to a crawl, and has twice brought my system to a halt. IE does not cause this, nor any other program I use, but the execution speed of all programs slows as badly as Firefox. If I knew where to get older versions, I would back up to 3.6.9 or earlier. The situation now prevents me from using Firefox much at all.

    Im running windows 7, Firefox 3.6.10 and before i updated to 3.6.10 my CPU never went above 10% with Firefox open. Now it can spike well above 50% and i have nothing different from when i had 3.6.9 to now when i have 3.6.10.
    There is no evidence for me to suggest one of the additions i have is causing it, its all pointing to Firefox itself and the last update.

  • How can I address a memory leak problem with Firefox?

    I have happily used Firefox for the past 7 years, and have rarely had difficulties. However, I am having some trouble now; Firefox (running 3.6.6) seems to have a memory leak on my machine. It's slower than what was discussed in other forum posts, but it still scales up slowly to multiple hundred MBs of Memory with very little CPU usage.
    I have tried disabling add-ons and extensions, but this does not stop the problem. I have cleared my cache and other stored data, but that also does not help. Has anyone experienced a similar problem that might be able to help?
    == This happened ==
    Every time Firefox opened
    == within last two weeks

    Hi reble0708,
    I have Java console disabled on my Firefox browser.Everything is working fine for me. There maybe other problem on your browser which is making PDF document faded and blurry. Can you post the link where you found the problem viewing the PDF document?
    Btw, you can go to ftp://ftp.mozilla.org/pub/firefox/releases/ and select the previous version of Firefox from the given options. There's no need to uninstall Firefox before you downgrade to the previous version of it.But before new installation, backup your Firefox profile folder.
    edit: replaced random unofficial download site link.

  • I am getting a memory leak that sometimes leads to an unresponsive Firefox, but does not crash per se.

    Hello, For the last couple of months, I am having issues with one of my tabs or the program itself causing a memory leak. I was hoping that subsequent releases would fix the problem, but when I downloaded V.11 it did not help.
    I use tab mix plus and at any time, usually have about 25 tabs open. Everything functioned okay for 8 or so months up until recently.
    I am wondering if there is a way to try to track down what is causing the leak. If it is one of my open pages, i will get rid of it. I tried opening one page at a time from scratch, but could not find the issue. .
    I always have flash block enabled to cut down on the website junk.
    using OSX firefox v11.

    Now, I'm not going to say it's an Add-On problem because from the research I've been doing on this problem for the last half hour shows that everyone has DIFFERENT add-ons, but everyone's having the SAME problem....
    So I went through my add-ons and disabled them one by one, and the single add-on that has been giving me grief is the latest WOT add-on. So, I have Firefox 11 (so does my wife) and we both have the WOT add-on. But that's where the similarity ends... I have Windows 7 x64, she has Windows XP x86.... but she doesn't have the memory leak problem.
    What I see is a sawtooth pattern over time. Memory goes up a little over 30+ seconds, then drops down. But over half an hour, the peaks of the sawtooth are larger, and it doesn't drop back down to the same level again - always a little more than before. And before you know it, FF is peaking at 1.5+GB, dropping down to 1.2GB... and FF is running very, very slowly.... excessive disk accesses (paging probably, though I apparently I still have 1.5 to 2.0 GB of free RAM). Killing FF frees it all up, and if I open FF again, it's back to using 250MB of RAM.
    So, it's not the add-ons per se, but how they're interacting with FF (or the other way round).... most likely, it's this plug-in container they created to stop add-ons from taking FF with them when they crashed. Seems to have created more problems than it has solved..... would be great if you could choose not to use it....

  • Allocated memory pool was not deleted! 1 GB memory leak is too much for me!

    Dear Sirs. I found that DB environment, that was configured to use 1 GB cache size, won't free it when closed! Why? First I tried to open and close environment and got the following:
    Detected memory leaks!
    Dumping objects ->
    {596} normal block at 0x01970040, 1048596 bytes long.
    Data: < > 14 00 10 00 DB DB DB DB 0B 00 10 00 01 00 00 00
    {578} normal block at 0x00397978, 464 bytes long.
    Data: < > D0 01 00 00 DB DB DB DB C7 01 00 00 01 00 00 00
    Object dump complete.
    I have and idea that BDB will reuse the memory, rite? OK, let's try to create the same environment and open it. After environment was opened, closed, opened again and again closed, I got the following:
    Detected memory leaks!
    Dumping objects ->
    {3663} normal block at 0x01B80040, 1048596 bytes long.
    Data: < > 14 00 10 00 DB DB DB DB 0B 00 10 00 01 00 00 00
    {3645} normal block at 0x00396E60, 464 bytes long.
    Data: < > D0 01 00 00 DB DB DB DB C7 01 00 00 01 00 00 00
    {596} normal block at 0x01970040, 1048596 bytes long.
    Data: < > 14 00 10 00 DB DB DB DB 0B 00 10 00 01 00 00 00
    {578} normal block at 0x00397978, 464 bytes long.
    Data: < > D0 01 00 00 DB DB DB DB C7 01 00 00 01 00 00 00
    Object dump complete.
    So memory was not reused, nor deallocated.
    By the way, you may be interested in other leak I found, but fixed, see
    Replication manager memory leak when setting local site information.
    This leak is more serious, I am not sure I will fix it quickly. Maybe I'm doing something wrong? Could you please suggest something?
    Thanks in advance!
    With regards,
    Vladislav.

    OK, the problem solved by fixing code in file 'log.c', method '__log_dbenv_refresh'.
    Just added the code that deallocates memory of bulk buffer.
    if (IS_ENV_REPLICATED(dbenv))
    if (lp->bulk_buf != INVALID_ROFF)
    __db_shalloc_free(&dblp->reginfo, lp->bulk_buf);
    lp->bulk_buf = INVALID_ROFF;
    lp->bulk_len = 0;
    lp->bulk_off = 0;
    It was allocated in the '__log_open' function, by the following code:
              lp->ready_lsn = lp->lsn;
              if (IS_ENV_REPLICATED(dbenv)) {
                   if ((ret = __db_shalloc(&dblp->reginfo, MEGABYTE, 0,
                   &bulk)) != 0)
                        goto err;
                   lp->bulk_buf = R_OFFSET(&dblp->reginfo, bulk);
                   lp->bulk_len = MEGABYTE;
                   lp->bulk_off = 0;
              } else {
                   lp->bulk_buf = INVALID_ROFF;
                   lp->bulk_len = 0;
                   lp->bulk_off = 0;
    Sorry for time taken to read my posts, I was really needy in quick help, but solved problems myself.

  • Pro*c multithreaded application has memory leak

    Hi there,
    I posted this message a week ago in OCI section, nobody answer me.
    I am really curious if my application has a bug or the pro*c has a bug.
    Anyone can compile the sample code and test it easily.
    I made multithreaded application which queries dynamic SQL, it works.
    But the memory leaks when i query the SQL statement.
    The more memory leaks, the more i query the SQL statement, even same SQL
    statement.
    I check it with top, shell command.
    My machine is SUN E450, Solaris 8. Oracle 9.2.0.1
    Compiler : gcc (GCC) 3.2.2
    I changed source code which is from
    $(ORACLE_HOME)/precomp/demo/proc/sample10.pc
    the sample10 doesn't need to be multithreaded. But i think it has to work
    correctly if i changed it to multithreaded application.
    the make file and source code will be placed below.
    I have to figure out the problem.
    Please help
    Thanks in advance,
    the make file is below

    Sample Program 10: Dynamic SQL Method 4
    This program connects you to ORACLE using your username and
    password, then prompts you for a SQL statement. You can enter
    any legal SQL statement. Use regular SQL syntax, not embedded SQL.
    Your statement will be processed. If it is a query, the rows
    fetched are displayed.
    You can enter multi-line statements. The limit is 1023 characters.
    This sample program only processes up to MAX_ITEMS bind variables and
    MAX_ITEMS select-list items. MAX_ITEMS is #defined to be 40.

    sqlnul() is used to reset the high-order bit of
    the datatype and to check whether the column
    is NOT NULL.
    CHAR datatypes have length, but zero precision and
    scale. The length is defined at CREATE time.
    NUMBER datatypes have precision and scale only if
    defined at CREATE time. If the column
    definition was just NUMBER, the precision
    and scale are zero, and you must allocate
    the required maximum length.
    DATE datatypes return a length of 7 if the default
    format is used. This should be increased to
    9 to store the actual date character string.
    If you use the TO_CHAR function, the maximum
    length could be 75, but will probably be less
    (you can see the effects of this in SQL*Plus).
    ROWID datatype always returns a fixed length of 18 if
    coerced to CHAR.

    so you need to set a maximum. In this example,

    Hi Jane,
    What version of Berkeley DB XML are you using?
    What is your operating system and your hardware platform?
    For how long have been the application running?
    What is your current container size?
    What's set for EnvironmentConfig.setThreaded?
    Do you know if containers have previously not been closed correctly?
    Can you please post the entire error output?
    What's the JDK version, 1.4 or 1.5?
    Thanks,
    Bogdan
