Solution for addons with memory leaks needed! (check / mark them)

The Problem with Firefox is that there are a vary of plugins from other developers, but it could not be that users have to live with growing memory usage or memory leaks by these addons. This gives also Firefox itself a bad impression and I think there should be a solution to stop the trend because as a user I can not always identify what's the problem now and why the firefox-process gives no memory free but it makes firefox partially unusable if I have to open more than a few tabs.
In my opinion also popular extensions that are used by a lot of people still have memory leaks or even the addon-developer does not know that his addon has one.
Is there no possibility that firefox helps, that addons can't produce so many memory leaks or otherwise Mark them in the Addon repository if they have leaks or memory problems?!

Being a rookie, I thought memory leaks weren't
something that java developers had to worry about.No managing memory is what you don't have to worry about.
That doesn't mean that your code still can't have memory leaks in it.
Now I'm starting to get java.lang.outOfMemory
Exceptions. My application just keeps eating up more
more ram until.... kaboom!The garbage collector can only clean up stuff that is no longer being 'used'. If you hold references to stuff that you no longer use, then you are creating a leak.
>
I think I get the ram back when the java app exits.
So I don't know, if this is technically a memory leak
or not. But It's a problem; Is there some way to
explicitly call the java garbage collector and then
recover from a OutOfMemoryException?
As I pointed out above, the garbage collector collects garbage. It isn't garbage until there are no more references. Leaks are caused by holding onto references even though they are no longer needed. The GC can't do anything about that.
I would appreciate any responce. (even if it's just a
one liner)
Since it sounds like you are creating a professional application I would suggest that you buy either JProbe and/or OptimizeIt and run your app through them. They will find memory leaks. And as an added benifit will also allow you to determine the bottlenecks in your application.

What is the best way to deal with memory leak issue in sql server 2008 R2

What is the best way to deal with memory leak issue in sql server 2008 R2.

What is the best way to deal with memory leak issue in sql server 2008 R2.
I have heard of memory leak in OS that too because of some external application or rouge drivers SQL server 2008 R2 if patched to latest SP and CU ( may be if required) does not leaks memory.
Are you in opinion that since SQL is taking lot of memory and then not releasing it is a memory leak.If so this is not a memory leak but default behavior .You need to set proper value for max server memory in sp_configure to limit buffer pool usage.However
sql can take more memory from outside buffer pool if linked server ,CLR,extended stored procs XML are heavily utilized

Try to restore your iphone via iTunes or update to ios6.1.2.
If itunes gives an error with restoring (DFU/Recovery or just normal)
try this:
open your computer and search on windows; C://windows/system32/drivers/etc/hosts
open up the hosts file in note pad you will see IP adresses and more add another line and put in this:
#74.208.10.249 gs.apple.com
this is a by-pass to the cydia/saurik restore server, it has nothing to do with jailbreaking over voiding apple's warranty
let me know if succeeded!

Are the lines in a text file? A RichTextBox? A TextBox? Some other control? A List(Of String)?
Is there some expectation by you that by providing what you wrote in your question post that the knowledge in your mind about what you are thinking about will mysteriously emanate to anybody reading your post so all of the sudden your knowledge will
become their knowledge and they will be able to provide you with an answer as they will suddenly understand what you are trying to do? Because that's probably impossible. Most people try providing enough information in a question so anybody, even stupid people
like me, can understand what they want. Maybe you should try that. As well as selecting an appropriate forum for your question in the future. Usually a question like this is related to programming in a particular language therefore a language forum may be
a good choice. Or not.

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 to deal with Memory Leaks, that are caused by Binding

Hi, I recently noticed (huge?) memory leaks in my application and suspect bindings to be the cause of all the evil.
I made a little test case, which confirms my suspicion:
import javafx.application.Application;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class TestAppMemoryLeak extends Application {
    public static void main(String[] args) {
        launch(args);
    @Override
    public void start(Stage stage) throws Exception {
        VBox root = new VBox();
        Button button = null;
        for (int i = 0; i < 100000; i++) {
            button = new Button();
            button.textProperty().bind(text);
            button.textProperty().unbind(); // if you don't call this, you can notice the increased memory of the java process.
        root.getChildren().add(button);
        Scene scene = new Scene(root);
        stage.setScene(scene);
        stage.show();
    private StringProperty text = new SimpleStringProperty("test");
}Now the problem is, HOW can I know, when a variable is no longer needed or overwritten by a new instance.
Just an example:
I have a ListView with a Cell Factory. In the updateItem method, I add a ContextMenu. The textProperty of each MenuItem is bound to a kind of global property, like in the example above. I have to do it in the updateItem method, since the ContextMenu differs depending on the item.
So every time the updateItem method is called a new ContextMenu is created, which binds some properties, but the old context menus remain in memory.
I guess there could be many more example.
How can I deal with it?

I've dealt with this situation and created a Jira issue for it, but I also have a work-around that is a bit unwieldy but works. I'll share it with you.
The bug that deals with this (in part atleast): http://javafx-jira.kenai.com/browse/RT-20616
The solution is to use weak invalidation listeners, however they are a bit of a pain to use as you cannot do it with something simplistic as "bindWeakly"... and you need to keep a reference around to the wrapped listener otherwise it will just get garbage collected immediately (as it is only weakly referenced). Some very odd bugs can surface if weak listeners disappear randomly because you forgot to reference them :)
Anyway, see this code below, it shows you some code that is called from a TreeCell's updateItem method (I've wrapped it in some more layers in my program, but it is essentially the same as an updateItem method):
public class EpisodeCell extends DuoLineCell implements MediaNodeCell {
private final WeakBinder binder = new WeakBinder();
@Override
public void configureCell(MediaNode mediaNode) {
    MediaItem item = mediaNode.getMediaItem();
    StringBinding episodeRange = MapBindings.selectString(mediaNode.dataMapProperty(), Episode.class, "episodeRange");
    binder.unbindAll();
    binder.bind(titleProperty(), MapBindings.selectString(mediaNode.dataMapProperty(), Media.class, "title"));
    binder.bind(ratingProperty(), MapBindings.selectDouble(mediaNode.dataMapProperty(), Media.class, "rating").divide(10));
    binder.bind(extraInfoProperty(), Bindings.when(episodeRange.isNull()).then(new SimpleStringProperty("Special")).otherwise(episodeRange));
    binder.bind(viewedProperty(), item.viewedProperty());
    subtitleProperty().set("");
}This code makes use of a class called WeakBinder -- it is a helper class that can make Weak bindings and can keep track of them. When you call unbindAll() on it, all of the bindings it created before are released immediately (although they will also disappear when the Cell itself is garbage collected, which is possible because it only makes weak references).
I've tested this extensively and it solves the problem of Cells keeping references to objects with much longer life cycles (in my case, the MediaNode passed in has a longer lifecycle than the cells and so it is important to bind weakly to it). Before this would create huge memory leaks (crashing my program within a minute if you kept refreshing the Tree)... now it survives hours atleast and the Heap usage stays in a fixed range which means it is correctly able to collect all garbage).
The code for WeakBinder is below (you can consider it public domain, so use it as you see fit, or write your own):
package hs.mediasystem.util;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javafx.beans.InvalidationListener;
import javafx.beans.Observable;
import javafx.beans.WeakInvalidationListener;
import javafx.beans.property.Property;
import javafx.beans.value.ObservableValue;
public class WeakBinder {
private final List<Object> hardRefs = new ArrayList<>();
private final Map<ObservableValue<?>, WeakInvalidationListener> listeners = new HashMap<>();
public void unbindAll() {
    for(ObservableValue<?> observableValue : listeners.keySet()) {
      observableValue.removeListener(listeners.get(observableValue));
    hardRefs.clear();
    listeners.clear();
public <T> void bind(final Property<T> property, final ObservableValue<? extends T> dest) {
    InvalidationListener invalidationListener = new InvalidationListener() {
      @Override
      public void invalidated(Observable observable) {
        property.setValue(dest.getValue());
    WeakInvalidationListener weakInvalidationListener = new WeakInvalidationListener(invalidationListener);
    listeners.put(dest, weakInvalidationListener);
    dest.addListener(weakInvalidationListener);
    property.setValue(dest.getValue());
    hardRefs.add(dest);
    hardRefs.add(invalidationListener);
}Let me know if this solves your problem.

Question for those with memory issues on k8n neo plat

I have been having issues with my memory on the k8n neo platinum board since i built the system last month and i just recently discovered a fact I had overlooked.
I Have discovered that if i test the system while it is cool (having sat turned off overnight for example), then memtest will pass the ram just fine and the system will be stable for a short period of time, generally longer if no intensive applications are used, ie. doom3 vs. websurfing).
This system, once it heats up ( seems mostly to be the nvidia 3 nb that needs to be "hot"- that is, a probe placed in contact with the module reaches about 58+ degrees c) then the system becomes unstable and memtest, if used, fails.
Prime95, if used on it when its cool, will usually take about an hour or so to fail, but if its used on the system when its been running a bit ( temps from nb at 58c+ and memory module hot to the touch) then it fails after about 20-30 seconds.
I have placed an active hs on the nb in an attempt to correct this, but temps still remain high with failures occuring.
I have spent the better part of three days testing the sytem this way and the above facts have held true in all these tests.
I have tested at stock ratings ( not using "auto" in bios, but using "approved ratings" of 10 x 200 for fsb and timings of 2-3-3-7 for my ram at 1:1 (which is recommended as well) since i am testing for base stability at this point;Voltages have been left at auto settings, however.
I was wondering if anyone else with memory issues could try this out and post if this seems to be the case for you as well.
Perhaps the memory issues on these boards are directly related to a problem with the nvidia 3 chipset running too hot?
Does anyone have a memory issue with these boards who is using water cooling on the NB ?
Lack of issues from people using 'problem" memory, but having no failures with water cooled nb's would support my assumption.

Yes i did mean chipset.
I am using a stock hs/fan from amd, which seems to run a tad hot but, considering that I wont overclock until I can get board stable, its not an issue. (runs 35-40 idle and up to 72 intensive). I need the warranty more then the extra mhz at present.
I removed the stock heatsink from the nvidia chipset and bought a generic chipset cooler (green, very little in the way of fins and seems to be aluminum) with a small fan.
I used a generic silver paste from Compusa to adhere both the cpu hs and the chipset.
I didnt lap either hs, just installed each as per instructions on artic silvers website (figured it had to go on the same way even generic).
I also bought a kingwin thermal center which i ran probes from to the cpu, case, and nb chipset.
I am not using it to adjust fans so those arent connected - its just a reference temp I can see at a glance, esp considering the funky bios reading this boards been known to give.
I assume from these responces that even a nvidia 3 250 chipset shouldnt get as hot as mine?
I asked about that from the retailer i bought this from but he seemed to think it was "ok" at 50ish celcius, but then again he didnt look too confident when he said it, lol.
Idle right now reads on Corecenter at 28 celcius for cpu and 33 celcius for the chipset, although, I have readings of 37 c and 43 c from the kingwin thermal center, which i believe to be more accurate.
My voltage reads at 11.67 for the 12v line at idle right now.
The psu i got is stick from the xblade case i bought in store. (http://www.xoxide.com/xblade2.html)
I have a dvd burner, cd drive, and two maxtor ide hd's attached to the system;The only card is the agp.
Is there a way to check and see if the cpu ispower starved? software monitor or even an external probe perhaps?
I havent put a probe on it, but the ram came in its own heatspreader, which gets very hot to the touch as well.
What temps should I be looking for on these items?

Help with memory leak using DAQmx & VB6

I'm using DAQmx 8 with VB6 to control an NI 6251 analog input board. The application calls for changing channel configurations as the system is running, thus there are many multiple create task/clear task calls. I've been trying to track a memory leak, so I've created a very simple VB app to help identify the source. I have a loop with the following calls in it:
DAQmxCreateTask
DAQmxAddGlobalChansToTask
DAQmxCfgSampClkTiming
DAQmxStartTask
DAQmxReadAnalogF64
DAQmxClearTask
I see a little over 1Kb leak per loop iteration. If I skip everything except the create task, add channels and clear task, it still shows a leak.
Am I doing something wrong? Should I not be calling CreateTask/ClearTask multiple times?
Thanks for any help.
mfrazer

Mfrazer,
You definitely don’t want to have CreateTask and subsequently
ClearTask in a loop, nor does it look like you need to for your application.
You only need on task, you just need to change the task, so there is no need to
create multiple tasks. So leave the CreateTask and ClearTask on the outsides of
your loop, and keep everything else on the inside of the loop and make the
changes you need to the task each iteration. Also you are going to want to have
a DAQmxStopTask after your read to make sure the task is stopped and in the
proper state to be reconfigured. I hope that helps.

Crystal Report Basic for VS 2008 Memory Leak

Hi,
I am having a problem with CR Basic for VS 2008. I can display a report, which I have linked to an DataSet in C#, but when I close the window, I seem to have a memory leak, as verified by process explorer.
I am doing the following when the report window is closing:
myReportViewer.ReportSource = null;
myReportViewer.Dispose();
myReportObject.Close();
myReportObject.Dispose();
GC.Collect();
Any ideas? I have a significant report that is generated and the memory leak is quite significant.
Thanks,

The memory management you are seeing is an artifact of how the framework manages memory allocations of managed dlls. These dlls are left in memory as it is expect that they may be used later on in your app and reloading these dlls would be a resource intensive process. It is difficult, if not impossible to unload managed dlls and there may not be a good solution. However I suspect that once the managed dlls are loaded, you will see the memory moving in the 38,860 to 40,812 range. This memory will not be freed by the framework until the application is terminated.
Couple of ideas:
1) Trying to find resources on the possibility of unloading managed dlls. Apparently there is a way, but it is cumbersome. Couple of years ago, one of my coworkers spent some time on the issue and eventually gave upu2026 Looking around a bit, I have found the following links that may be of some use to you:

2) Try to see how the latest version of Crystal Reports behaves in your environment. Initially, I would suggest a test on a clean system with an eval version of Crystal Reports 2008. In CR 2008 we manage the memory via the crheapalloc.dll. So the behavior may be different. You can even try to see how CR 2008 behaves without the dll by simply renaming the dll.

Huge Memory Leak - Need help.

Hi,
There is a huge memory leak in our application. Because of this there are frequent session timeout. When we analysed the heap dump using Memory Analyser Tool, we got the leak suspects and the problem suspects are as below:
One instance of "org.apache.jasper.compiler.JspRuntimeContext" loaded by "org.apache.catalina.loader.StandardClassLoader @ 0x87ff8098" occupies 161,832,200 (23.30%) bytes. The memory is accumulated in one instance of "java.util.concurrent.ConcurrentHashMap$Segment[]" loaded by "<system class loader>".
One instance of "org.apache.catalina.tribes.tipis.LazyReplicatedMap" loaded by "org.apache.catalina.loader.StandardClassLoader @ 0x87ff8098" occupies 133,578,920 (19.23%) bytes. The memory is accumulated in one instance of "java.util.concurrent.ConcurrentHashMap$Segment[]" loaded by "<system class loader>".
185 instances of "org.apache.jasper.runtime.BodyContentImpl", loaded by "org.apache.catalina.loader.StandardClassLoader @ 0x87ff8098" occupy 133,502,776 (19.22%) bytes.
What could be the root cause for this error and how to resolve this?

First, in general you not provided enough details to get any help. OS? OS version? Hardware specifics?
Second, are you running custom code? If so, post it so you can get help.
Third, if you're not running custom code, the odds of you having a "huge memory leak" are pretty small.

Hi fkr2.0,
Welcome to the world of iPad deployments! There are a few things I recommend you do before you get started:
First I would watch the iOS Deployment Model Videos on the left side of this page:
http://www.apple.com/education/resources/information-technology.html
Then I recommend you read through these two guides:
iOS 6 Education Deployment Guide
http://images.apple.com/education/docs/ios_6_education_deployment_guide.pdf
Apple Configurator Help Guide
http://help.apple.com/configurator/mac/1.0/
This will give you a solid foundation for managing iPads with Apple Configurator. Once you read through these guides you will likely have more specific questions that you can post to these forums.
Hope this answers your question!! Good luck with your iPad deployment.
