  • HTTPService + XML Load + Memory Leak

    Hi all....
    I have noticed a memory leak in my application. This leak was
    not apparent when the application was completed some months back
    which is what left me a little confused as all I have done since
    was upgrade to Flex 3 and possibly updated / changed my Flash
    player.
    I think I have found the cause to this problem (below) but am
    not 100% sure that it is the "actual" problem or any reasons to
    back my thoughts up, so have listed what I have checked / tried
    along the way (maybe I have missed something)....
    My Discovery Process:
    I started profiling my application but did not find anything
    out of the ordinary. I did a code walk-through double checking I
    had cleaned up after myself, removing and even nulling all items
    etc but still to now success - the leak is still there.
    I have profiled the app in the profiler for reasonably long
    periods of time.
    All the classes etc being used within the app are consistent
    in size and instance amount and there is no sign of any apparent
    leak.
    I am using a HTTPService that is loading XML data which I am
    refreshing every 5 seconds. On this 5 second data refresh some
    class instances are incremented but are restored to the expected
    amount after a GC has occurred. The GC seems to take longer, the
    longer the app is running, therefore more and more instances are
    being added to the app, but when the GC eventually runs it "seems"
    to clear these instances to the expected amount.
    After scratching my head for a while I decided to make a copy
    of my application, rip everything out, and focus in my data load,
    where I found a problem!
    I have now just a HTTPService that loads an XML file every 5
    seconds, and this is all I currently have in the app (as I ripped
    the rest of the code out), e.g:
    Code:
    <mx:Application xmlns:mx="
    http://www.adobe.com/2006/mxml"
    ....... creationComplete="initApp()" >
    <mx:HTTPService
    id="httpServiceResults"
    url="
    http://myIP:myPort/myRoot/myXML.cfm"
    resultFormat="e4x"
    result="httpResultHandler(event)" />
    <script....... >
    private var timerPulse:Timer;
    private function initApp():void
    httpServiceResults.send();
    timerPulse = new Timer(5000, 0);
    private function httpResultHandler(event:ResultEvent):void
    timerPulse.start();
    timerPulse.addEventListener(TimerEvent.TIMER, timerRefresh);
    public function timerRefresh(eventObj:TimerEvent):void
    timerPulse.stop();
    timerPulse.removeEventListener(TimerEvent.TIMER,
    timerRefresh);
    timerPulse.reset();
    httpServiceResults.send();
    </script>
    </mx:Application>
    This is pretty much the code I am currently using and it
    leaks.
    I ran and monitored this in both the profiler and the
    activity / task manager, and after running the app for 1800 seconds
    (30 min) in the profiler, the memory size grew from 50mg to 165mg
    just sending the HTTPService.
    I tried loading the service in multiple ways including in AS
    rather than MXML creating new instances of it each time, resetting
    it, nulling it etc... but nothing prevented this memory increase.
    I then tried to load the XML using different methods such as
    using the URLRequest and URLLoader which again caused a memory
    leak.
    What still confuses me is that this leak did not exist in the
    previous version and not a great deal has changed since then apart
    from upgrading to Flex 3 and possibly upgrading my Flash payer
    (which I believe is a possible cause)
    After looking into this issue a bit more deeply, I read a few
    blogs / forums and other people are experiencing the same problems
    - even with a lot bigger leaks in some cases all when reloading
    large sets of XML data into Flex - however, I as of yet found no
    solution to this leak - people with a similar problem believe it is
    not due to a memory leak more a GC error, and others pointing
    towards the Flash Player itself that is leaking - I don't really
    know.
    Findings so far during investigation of this issue:
    * App leaks for both HTTPService and ULRRequest / URLLoader
    methods
    * App only leaks when calling a data loader
    * The size of the leak seems to depend on the size of the
    XML being loaded
    * The size of the leak also seems to be affected by the
    applications heaviness - the greater seems to enhance the leak
    An interesting factor I have noticed is that if I copy the
    XML from my "myXML.cfm" that I link to in my HTTPService and copy
    the contents of the file into my own XML file stored within the
    Flex project root itself: ""myXML.xml"" the leak disappears... like
    it seems to link when loading the XML over a network, however as my
    network knowledge is not great I am not sure what to make of this -
    any ideas???
    Could the connection to the XML document cause leaks??? is
    there anything else that could cause this leak??? have I something
    in my code sample that could cause this leak??? or could any of the
    other things I have mentioed cause this leak???
    Any help / ideas would be greatly appreciated.
    Thanks,
    Jon.

    I also observed heavy memory leak from using httpservice with
    XML data. I am using Flex3 builder under Linux. My Flex application
    polls httpservice every 10 seconds. The reply is a short XML
    message less than 100 bytes. This simple polling will consume 30+
    MB of memory every hour. I leave it idling for several hours and it
    took 200 MB of memory. No sign of garbage collection at all.

  • Memory Leak in UIWebview on loading NSURLRequest

    I have created a custom browser for my app. Whenever i load a url request into web view a memory leak is seen. A snapshot of the same is shown below
    Please note that no backtrace has been shown which makes life more painful. In my application a simple webview is shown and a refresh button is given below webview. A snapshot of same is shown below

  • Memory leak? Firefox won't load pages/open.

    Ok, I believe there is a memory leak. I am surfing ok then a page wont load. I go to taskmgr and I show that one firefox has 104,990 K of memory. The rest have at most 3,000K. After the page won't load I close Firefox. It won't open. I have to turn on PC and unplug to get it to open again.

    This issue can be caused by an extension or plugin that isn't working properly.
    Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    * Don't make any changes on the Safe mode start window.
    See:

  • Crystal Reports 2008 - Report Load error - Memory Leak Error?

    Hello
    <br>
    We have a problem with Crystal Reports 2008 with .NET 2.0.
    <br>
    CrystalDecisions.CrystalReports.Engine, Version=12.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304
    <br>
    The problem is that during high amount of report producing, errors in eventlog pops up and the production of reports using <br>
    Crystal Reports stops.
    <br>
    Below are examples of the three most common event logs.
    <br>
    We have tried to implement a cleanup method both as a destructor (with a global ReportDocument rdoc variable) and using direct call to cleanUpDoc() method when finished with loading doc:
    <br>
    ~IOServerClass()
    <br>
    <br>
                cleanupDoc();
    <br>
    <br>
    <br>
            private void cleanupDoc()
    <br>
    <br>
                try
    <br>
    <br>
                    if (rdoc != null)
    <br>
    <br>
                        rdoc.Close();
    <br>
                        rdoc.Dispose();
    <br>
                        rdoc = null;
    <br>
    <br>
                    this.CleanGlobalEvents();
    <br>
                    System.GC.Collect();
    <br>
    <br>
    <br>
    <br>
    The doc is loading using the "normal" method (in-process).
    <br>
    <br>
    try
    <br>
    <br>
                        rdoc = new ReportDocument();
    <br>
                        rdoc.Load(fullpathandreport); 
    <br>
    <br>
                   catch (Exception ex)
    <br>
    <br>
                    cleanupDoc();
    <br>
    <br>
    ...process doc....
    <br>
    cleanupDoc();
    <br>
    <br>
    Furthermore we have tried during Scalable tests of the system - but cannot produce the below errors ourselves. Only the customer can.
    <br>
    Please help with solving this problem.
    Is the above advisable to do?
    Should the document be loaded in another way?
    Is it a memory leak?
    <br>

    Kristian

    Hi;
    First, ensure you have the latest service pack / hot fix for your version of Crystal Reports, and that the client has the same updates as well. Fix Pack 2.4 is the current latest, and can be downloaded from our downloads section.
    One of the errors is the Background Processing error, so have a look at the following article:
    http://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/50a6f5e8-8164-2b10-7ca4-b5089df76b33&overridelayout=true

  • Memory leak problems with loading videos over and over.

    I'm having memory leak problems with loading videos into a VideoPlayer aswell as FLVPlayback.
    What the flash should do:
    - Should be running for 7 days without having to restart the projector.
    - Interface that shows people around a 360 3D model with 5 different parts and at the stops it makes during the rotation you can click to zoom in on a location which plays a movie for that aswell.
    - Shows a video out of 5 parts for a 360 rotation in 3D in mp4 video (added each time and cleaned up, see code below).
    - Still images are used when the video clips are done playing (MovieClip in stage).
    - Should run automatically when there is no user interaction for X minutes.
    What the problem is:
    - The flash (as a exe and swf i guess) starts to consume memory over time (say 10 hours) until the projector crashes. This usually at around 1.75 GB of memory.
    I cannot see why the Flash cannot garbage collect this and free up the memory. Mabye there is something I don't understand about the garbage collection in flash?
    Here is some code from the video loading and playing:
    var fVideo:VideoPlayer;
    VideoCreate();
    function VideoReady(pEvent:VideoEvent):void
    trace("VideoReady()");
         // start playing video
    fVideo.play();
    function VideoLoad(pUrl:String):void
         trace("VideoLoad(" + pUrl +
         VideoCreate();
         if (pUrl != "")
              if (fVideoFolder + pUrl == fVideo.source)
                   fVideo.seek(0);
    VideoReady(null);
              } else {
    trace(fVideo.state);
                   if (fVideo.state !=
    VideoState.DISCONNECTED) fVideo.stop();
    fVideo.close();                                
    fVideo.load(fVideoFolder + pUrl);
         } else {
    // error no url

    Hmm. It's in connection with Dropbox. Så apparantly you can only use one of the two at the same time if you want the programs integrated in Finder.

  • [iPhone] Memory leak when UIWebview is loaded with URL

    I have created a custom browser in my app using UIWebview . A memory leak is seen on everytime webview is loaded with provided  url. A snapshot of the leak is shown below.You may note that no back trace is shown and hence cause of leak is unknown.
    Snapshot of leak
    Please help me with this issue as early as possible.

    You might want to take this discussion to the developers forums. This is a general user to user forum for using the iPhone. This is way outside the scope of general use.

  • Adobe AIR memory leak loading SWFs

    I was plagued by a memory leak that would crash my application after a few hours. The application had worked fine in the past but now was having issues and I thought it might have to do with using newer SDK's.
    In the end I discovered that if I loaded external swf that had been compiled in debug mode, they would not clear completely on unload and cause a memory leak.
    Compiling in release mode fixed the issue. Spent 3 days trying to figure it out.

    Any chance you can check that out with the latest AIR?
    Either way, it sounds like a bug, please report it at http://bugbase.adobe.com/ and then report the bug number here. 
    If you're able to provide a reproducable case that would really increase the chance that we can do something about it.
    Thanks,

  • Applet load and memory leak

    what are some methods to load an applet faster that is on the local machine? also, are there any applications to test for memory leaks? and are there ways to invoke garbage collection with code? thanx in advance.

    Applet on the local machine will load faster because file is already there
    use System.gc() to do a garbage collection

  • 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).

  • APEX 4.1.1 Memory Leak in IE7

    Hi,
    We busy upgrading our apex and db from 3.0/10G to 4.1.1/11.2G and notice that there appears to be a memory leak when using APEX. At one stage we have had IE7 using over a gig of memory.
    When you load or refresh your page IE7 seems to grab on average 2-5MB of memory for each page load. At first we thought it may have been our apps or setup but this also happens when we go to app 4550 page 1 on apex.oracle.com.
    How to replicate:
    Open task manager to view the Memory Usage.
    Using IE7
    1. Go to http://apex.oracle.com/pls/apex/f?p=4550:1
    2. Go back to Task Manager and note the readings once the CPU Usage for iexplore.exe has stablised to 0.
    3. go back to IE7 and press F5
    4. Repeat steps 2-3 and you will see the Memory usage increases.
    We think this maybe due to a few jQuery UI memory leaks within IE7 and thought this bug ticket maybe of interest http://bugs.jqueryui.com/ticket/7666 (Slightly different versions but similiar experiences)
    Could someone else confirm that they also experience the increasing or have had similiar problems and managed to resolve it?
    TBH, it wouldn't be an issue to use another browser like Firefox to access the builder but this also affects the applications if they include APEX standard Javascript and CSS.
    Thanking you in advance.

    Could someone else confirm that they also experience the increasing or have had similiar problems and managed to resolve it?Anecdotally, yes. Don't have exact steps for replication or precise numbers, but I have noticed this in passing. On the junk that my client considers a PC suitable for web development the typical IE7 memory footprint with the APEX 3.0 builder and several other tabs running is about 52MB. Add APEX 4.1.1 and it climbs constantly until I have to pull the plug when it gets north of 150MB as the PC can't take it.
    As well that I also have Firefox and 4.1.1 is still experimental at that site...
    At the moment I don't have to resolve it and if I did the only option I'd propose is the replacement of IE7.

    I saw that eariler this week. I do agree with the concept though.So take appropriate action: charge extra for IE7 support.
    The amount of work and effort involved in making our website look normal on IE7 equalled the combined time of designing for Chrome, Safari and Firefox.Is entirely accurate. If it's stated as a requirement, itemise it as an extra on the quote.
    Educate management and bean counters: show them the one line of standards-compliant CSS that's all that is necessary in Safari, Chrome, Firefox and Opera (and just possibly in IE8/9/10), how it isn't supported in IE7, and the tortuous hacks and workarounds that are required to get something equivalent working there.

  • How Do I identify a Memory Leak?

    I know this is not enought information but...
    My application used 3 hashtables in a Data object to store application data. I retrive this data from an XML file. I also download XML and merge it into andother XML file. Some of these hashtables contain object that contain more hashtables.
    I am trying to use JProbe Profiler to find the leak. I notice the memory increases when I load the data into objects and put them into hash tables. I also notice an increase when I am merging newly downloaded XML into the current XML data. I am useing Nodelists and NOdes to get the data.
    Does anyone have any tips or suggestion on how to find a memory leak?
    Thank you,
    Al

    7 MB of XML file, loaded into a DOM? You realize, of
    course, that DOMs are data structures that take up
    memory, too, right?Yes I do. I load it into DOM then go through the Document and put the XML data into a custom file format (seialized objects). The data is sent from the server in the form of XML.
    There's your problem. If you load X MB into memory
    and keep it around as long as your application is
    running, that's not necessarily a "leak". Yeah I realized this but it seems that if I load 7MB of my objects into hashtables my memory usage shouldn't increase by 30MB. I just assumed it would stay around 10MB.
    The real issue is trading memory for CPU. If keeping
    them in memory is crashing your app with OOM errors,
    by all means just keep those objects in memory for as
    long as you need them and then let the GC clean them
    up. Don't put them in a Map, just let them have a
    narrow method scope. Recreate them every time you
    need them. Yes I'm beginning to see the light.
    I'm sure you're thinking, "But recreating them will
    cost CPU and slow down my app!" Yes, that's why it's
    a tradeoff between memory and CPU.
    Do you really need the whole document in memory at
    once? If you're just cherry picking a few values out
    of it, maybe you can use a SAX parser instead of a
    DOM.
    No I don't need all that data at once.
    >
    Either you're screwed or you need to rethink this.
    You'd better hope that it's really not needed at
    every moment for every client.After rethinking, I'm going to keep the serialized data in the file until I need it. Rather than searching through a hashtable for the object I want I will search the file.
    What are your JVM settings for -Xms and -Xmx? Maybe
    increasing those will do the trick.I did increase them and it helped a little, but I can still get a OutOfMemoryError if I try.
    Are you sure these are the culprits? Have you
    profiled the app to see if there are other sources of
    leaks?Yes I have been profiling the application. It seems that there is a memory leek. I am just having trouble identifing it. I know the memory increases at 2 points. When I load the XML data into the DOM and when I load the DOM into my Custom object and then into the Hashtables.
    Last resort? Buy more physical memory. It's cheap.I think I am going to keep unused data out of memory and access it form a file. After I make this change I think my memory usage will drop alot. I will profile again after I have this change made to see if there is a memory leak.
    Thanks for you help,

  • DI API objects0-memory leak

    Dear All,
    We have created a application to load AR Invoice and Incoming Payment through PowerBuilder.
    While using DI API there is a memory leak.
    ie.,After loading say 500 AR invoices and corresponding payment, the application seems to hang but after some time its processing fine.
    While adding each invoice,in the task manager the memory usage is increasing proportionally for that application.
    We found that while using DI API objects, the issue is produced.
    We are using SAP B1 2007B PL08.
    Any suggestion on this issue?

    Hi Jambulingam,
    I've seen other developers complaining about the same problem.
    Take a look at this post. It may help.

         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 ??
    [jboss@jboss-new bin]$ jrcmd 17114  print_memusage

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

    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.

    Unfortunately not. No groups and any Mobile Me account here not even many contacts (436) and any duplicates except in Ical after having restored my iphone 4 times. Something strange too, 2 weeks ago, Isync was running while I'm not registered on MM nor Icloud (turned off on my iphone) . Maybe a conflict between Outlook, Addressbook, Itunes and Isync on SL....I'm going crasy with this issue It reminds me of Windows ! Thx anyway, I'm gooing to contact apple in the following days.
