ADF 10.1.3.4 Memory Leak

I can re-produce a ADF memory leak in jdeveloper. The problems seems to be when I am running the application locally in the memory profiler, the memory usage keeps growing until the application halts with a outofmemoryexception. The main problem seems to be object references to the jspx page object (_index_jspx._jspService : line 989) under the char[] object when the application get loaded with 20 concurrent users for about 10 mins. I have tried adjusting both heap and max perm gen sizes higher and re-tested but it still seems to get hit with the outofmemoryexception after 10 mins longer duration.
This is 1 very simple ADF page which accesses a read-only ADF BC view object with no other customizations. ADF is NOT scaling well in our load and performance tests.
Here are details about my environment:
Windows XP service pack 2
Intel Core 2 Duo process @3.16Ghz
4 GB of ram
Jdeveloper 10.1.3.4.4270
Jheadstart 10.1.3
Oracle 11g database
I can provide a dump of the memory profiler statistics at the point of failure if it is necessary.
This is a critical issue for our team so please advise me on how to solve this asap. Thanks.

The first thing to check is whether you can reproduce this behavior when you are running your application on a stand alone OC4J and not on the embedded OC4J in JDeveloper.
If you can reproduce this problem then please contact support and open an SR with the test case.
We have many customers using ADF 10.1.3 with more than 20 concurrent users.

ADF Memory Leak

hi all again.
I have two pages the first welcome.jspx and the second customer.jspx. In the first page users enters a cutomer number and post the number to the second page.
The second page loads cutomer information using the customer number. Users chages the informations and save the customer data. When the users click save button customer information saving and returning the first page. And this happens regularly.
When returned the first page what happens the data in the previous customer.jspx. Does the data reside or remain in memory?
I am using Toplink to load the data.
Thanks to all.

Are you asking a question about TopLink caching. I don't see a memory leak described here? If that is what your asking, please provide more details to your question and change the title of your thread to better represent your question.

Memory Leaking message when run the log in page in Jdev 11.1.2

Hi
I am re design our 10g application in Jdev 11.1.2, I am using .jsf and ADF business component.
at the moment, the project has only two pages. login and home page.
when I run the login page, I see the message below. this is happening during the deployment process to the embeded weblogic
<ADFContext> <getCurrent> Automatically initializing a DefaultContext for getCurrent.
Caller should ensure that a DefaultContext is proper for this use.
Memory leaks and/or unexpected behaviour may occur if the automatic initialization is performed improperly.
This message may be avoided by performing initADFContext before using getCurrent().
For more information please enable logging for oracle.adf.share.ADFContext at FINEST level.
Anyone know why?
thanks

Hi Timo
Thanks for your reply, I read the thread you pointed to.
however, I am not sure my is related to the case mentioned. I am re design the application from scratch in Jdev 11.1.2, and my adfc-config.xml is as simple as this:
<?xml version="1.0" encoding="windows-1252" ?>
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">

</managed-bean>
</adfc-config>
also, I am using a session filter registered in web.xml --- basically, if the page is not Login.jsf then redirect to Login.jsf page. but even though I removed the session filter.java from the web.xml , it still show the message.

Memory leaks

Hi.
I have a problem with the use of memory of my application. It has graph and pivottable components with bean classes that manages them. These classes are defined at level of session. It suposes that the instances of these classes will be erased by the garbage collector when i invalidate the session, but it doesn't happen and the memory remains busy.
I see with jmap and jhat that there are some ADF classes that reference my instances and i don´t know how can i remove these references. I've tried to use FacesContext.release(), but i've had problems with its use and i don't known where i can use this method.
Thanks!

Hi.
I still have the same problem, but now i've changed the numbers of instances that are saved into session scope. They are only 3, but the whole application is referenced by these three instances and take up much space.
I've read that the static members may produce memory leaks, but all of my static members are generic types.
I've tried to clean up my session scope by removing session attributes before finishing session.invalidate(). I do this into the HttpSessionListener.sessionDestroyed().
ExternalContext ectx = FacesContext.getCurrentInstance().getExternalContext();
HttpSession session = (HttpSession) ectx.getSession(false); //referencia
try {
ectx.redirect("login.jsp");
FacesContext.getCurrentInstance().responseComplete();
} catch (Exception ex) {
try {
ectx.redirect("error.jsp");
Logger.getLogger(GestorCM.class.getName()).log(Level.SEVERE, ex.getMessage(), ex);
} catch (IOException ex1) {
Logger.getLogger(GestorCM.class.getName()).log(Level.SEVERE, ex1.getMessage(), ex1);
try {
session.invalidate();
FacesContext.getCurrentInstance().release();
auxiliar.MyHttpSessionListener.InnerFacesContext.setFacesContextAsCurrentInstance(null);
} catch (Exception ex) {
Logger.getLogger(GestorCM.class.getName()).log(Level.SEVERE, ex.getMessage(), ex);
And HttpSessionListener.sessionDestroyed():
String var = (String) session.getAttributeNames().nextElement();
while (session.getAttributeNames().hasMoreElements()) {
var = (String) session.getAttributeNames().nextElement();
session.removeAttribute(var);
I don't know if these things that i'm doing are correct and i don't know if i have to configurate something to avoid memory leaks in ADF.
PD: I have problems with FacesContext.getExternalContext() after this.
PD2: I'm working with Tomcat 7 and ADF 11.1.3.
Thaks for all.

How can I avoid memory leak problem ?

I use Jdev 10.1.2 . I have a memory leak problem with ADF .
My application is very large . We have at least 30 application module , each application module contain many view object
and I have to support a lot of concurrent users .
as I know ADF stored data of view object in http session .
and http session live is quite long . when I use application for a while It raise Ouf of Memory error .
I am new for ADF.
I try to use clearCache() on view object when I don't use it any more .
and call resetState() when I don't use Application Module any more
I don't know much about behavior of clearCache() and resetState() .
I am not sure that It can avoid memory leak or not .
Do you have suggestion to avoid this problem ?

ADF does not store data in the HTTP session.
See Chapter 28 "Application Module State Management" in the ADF Developer's Guide for Forms/4GL Developers on the ADF Learning Center at http://download-uk.oracle.com/docs/html/B25947_01/toc.htm for more information.
See Chapter 29 "Understanding Application Module Pooling" to learn how you can tune the pooling parameters to control how many modules are used and how many modules "hang around" for what periods of time.

Memory leak? & ie7 partial triggers

Hi all,
I'm running Jdev 11.1.1.0.3 against a 10.3 WLS
I've made a few try with adf faces & I'm running now against a problem looking like memory leak.
I'm working with a parent/child tables in separate showdetailitems container having about 5/6 columns on the child table.
When I run the application it works perfeclty.
If I put 10/12 columns on the child table the application stalled when I go in the child showdetailitem (Retrieving data)
Except if the child table doesn't have more than 3-4 rows (then it works great)
I have another problem with IE7 making objectRequired error on any adf page with partialtrigger.
IE7 say the error is located arround the lines
this.headers= new Object();
this.xmlhttp= new XMLHttpRequest();}
AdfXMLRequest.prototype.toString=function()
in _all-11.1.1.0.0.js file
Any hint on any of the two would be appreciated, I'll try re-installing ie7 meanwhile. ^_^

hi Frank (great tutorials!), Peter.
Frank, Regarding ie7 I've noticed we're not a lot to have this problem, I use firefix meanwhile hoping ie8 fixes the issue. Still I'm ready to fill a SR if you think it's worthwhile.
Peter, Thx for the idea, i've set contentdelivery to immediate & get further errors ^_^
When I clic on the ShowdetailItem (third one) It goes back to the first one with this error (sorry you'll guess I'm french)

When I don't have too much rows, it's still working perfectly

ListOfValues Cancel button creates memory leak

I believe one nuance of the listOfValues element (in an LOV page) gives rise to a memory leak. The examples and listOfValues documentation shows storing data needed by listOfValues events in the session. This is all fine and good if the user clicks on the "Select" button, as you get both a lovSelect and lovUpdate event to work with and clean out session data. But in the case of a user clicking the "Cancel" button, no event is fired, nor is a forward to another DataAction done. The window is simply closed. This strands all the data for the LOV (which could be quite sizable) in the user's session. You can't send this data on the request, because the LOV data must exist across several requests.
Am I completely missing something? How does one clean out a user's session when the Cancel button is clicked on a listOfValues component?
Brad

I am using JDeveloper 9.0.5.2. The restrictions of the project prevent using a newer version of JDeveloper. I am using ADF/Struts, and pure UIX (no JSPS).
The functionality I am speaking of is the standard behavior of the <listOfValues> component (lov for short). The lov component generates events for various behaviors (lovFilter, lovUpdate, loveSelect, etc.). It also completely encapsulates the Cancel and Select buttons, so you have no direct access to those. In order to manage an lov web page (presumably launched from an <lovInput> component on a previous page), the events need access to a certain collection of data (data for the table, max size, starting row, selection, validity, etc.). Because use of the lov page will result in potentially multiple submits, the request is not a good place to store this data, as the data needs to persist for the life of the lov page.
If you look at some of the lovInput/listOfValues examples on the OTN, you'll see that this data is persisted in the user's session. In and of itself, this is fine.
The problem is introduced by the fact that the lov's Cancel button (or window close) does not generate any events, and you don't have direct access to those controls to add an event of your own. When the cancel button is clicked, the window just closes, and in the words of the lov documentation "no other events occur."
This is very problematic -- your session is still stuffed full of data to support the lov. I am looking for a way to remove that data.
Frank -- in your post, you say:
"why can't you add an event to clean the session from the data?"
If you know how to add such an event -- one that fires when the Cancel button is clicked, please enlighten me. I would greatly appreciate it!
Thanks,
Brad

Memory leak when browsing through records

Hello,
I have a problem with any page containing the component related to each other on three or more levels. (1st level ADF Table, 2nd level ADF Table and 3rd level ADF Form)
By navigating through the records of the first level, there is refreshment at other levels (using partial triggers), but suddenly there is loss of memory (memory leak) for components of type Select One Choice.
Precisely, the problem appears when browsing another Show Detail Item in the same page.
Screenshot showing the Data Control in my page: [http://www.infotun.net/usersimages/1/adf/structure.jpg]

Hi,
the screenshot does not indicate a memory leak. Memory leaks show by the server memory consumption that leads to slow performance or stale applications. Your issue seems to be different from that and doesn't really explain in the screen shots. If you have a support contract then customer support is the recommendation I like to give

Jheadstart 10.1.3 Memory Leak Problem

Hello,
I have encountered a re-produceable memory leak in ADF jheadstart in jdeveloper. The problems seems to be when I am running the application locally in the memory profiler, the memory usage keeps growing until the application halts with a outofmemoryexception. The main problem seems to be object references to com.sun.faces.ExpressionInfo$JSPExpressionString.<init> : line 192 under the char[] object when the application get loaded with 20 concurrent users for about 10 mins. I have tried adjusting both heap and max perm gen sizes higher and re-tested but it still seems to get hit with the outofmemoryexception after 10 mins longer duration.
I followed the step-by-step jheadstart tutorial as described here:
http://www.oracle.com/technology/products/jdev/tips/muench/jhstutorial/index.html
These are basic jheadstart pages with no customizations that are NOT scaling well in our load and performance tests.
Here are details about my environment:
Windows XP service pack 2
Intel Core 2 Duo process @3.16Ghz
4 GB of ram
Jdeveloper 10.1.3.4.4270
Jheadstart 10.1.3
Oracle 11g database
I can provide a dump of the memory profiler statistics at the point of failure if it is necessary.
This is a critical issue for our team so please advise me on how to solve this asap. Thanks.

Hello Steven,
Thanks for the quick reply.
We are using the jheadstart 10.1.3.3.81 build. The testing actions are very simple. I continuously load one page with concurrent users.
I actually performed 2 load tests using a jheadstart generated version and a pure ADF drag-and-drop version and unfortunately they show the same behavior. This is the reason why I started two separate threads (one for jheadstart and one for pure ADF) hoping that someone else has encountered such issues.
In both cases, at about 20 concurrent users using the oracle application testing suite, they both suffer from high memory usage of the char[] object and the Object[] objects which eventually ends with outofmemoryexception.
In the jheadstart version, the problematic referring object from char[] is com.sun.faces.ExpressionInfo$JSPExpressionString.<init> : line 192.
In the pure ADF version, the problematic referring object from char[] is indexjspx._jspService : line 989.
According to these tests, it seems that the problem lies at the ADF/JSF layer but if you have any insights, any help would be appreciated. Thanks.

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?

Memory Leaks   Unresponsive Mouse

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

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.
