Memory leak: critical (blocker) bug with unloading SWF with Vector. T

Here's the original bugreport https://bugbase.adobe.com/index.cfm?event=bug&id=3071138
dated december 2011 (add actually appeared even earlier). Despaired of getting any Adobe's team attention I even submitted it again today (as of new releases of FP 11.3 and AIR 3.3 betas).
Chris Campbell, seems like u're active on this forums. Can you give any feedback?

This bug has definitely been around a while.  The good news is that it's currently slated "Open / To Fix" for our AIR 3.3 release which is currently up on labs.adobe.com  (our internal number is 3072792).  We've been able to reproduce the problem and our development team is actively investigating.
The best way to make sure this gets continued focus is to recommend to everyone you know who is affected by this bug to take a minute and cast their vote on the public bug.

  • Blocking bug with 10.8.3+Adobe Lightroom+Canon iPF5000 (but workaround found)

    Hi all,
    since I have updated my MacBook Pro (early 2011 model) with 10.8.3, I have a blocking bug with Adobe Lightroom (either 4.3 or 4.4) for launching prints on my Canon iPF5000 (firmware 1.33, either MacOS driver 2.67 or 3.06, connection through USB).
    When I was under 10.8.2 with the Canon's driver 3.06, everything works fine.
    Basically, after clicking Print a Copy or Print... in Lightroom, the file spooled to the driver stays in MacOS printer queue. Within the printer queue window, the printer is in pause mode, and each time I try to resume the printing processing, the driver put it on hold immediately. When I look into the history on the Console, the driver complains about an unknown error... The data stay within the driver, as my Canon iPF5000 "Data" led indicator stays unlit.
    My print settings are 600dpi or 300dpi, print sharpening Standard/Glossy, 16 bit output. And Color managed by printer (because I let the Canon driver managing my B&W prints).
    Strangely enough, when I launch a print from Preview application, the drivers does its job and sends it successfully to my Canon iPF5000...
    As this was driving me crazy, I have tried a clean install of MacOS 10.8.3 (as 10.8.2 is no more available from Apple servers...). No success, same blocking issue.
    Eventually, I've found the workaround: using the imagePROGRAF Advanced Preview. You have to click on "Print..." in Lightroom in order to see the driver settings window, and then check the "Preview before printing" option in the main tab of the driver settings. Then I can preview my Lightroom printing work and then launch successfully my printing.
    Simple workaround, but very strange bug...
    For me, the root cause could be multiple and not very obvious.
    Is it Mac OS 10.8.3 ? But why can I make prints from Preview application for instance, and not from LR ?
    Is it the Canon driver ? But this lead me to the same question.
    Is it Lightroom ? Does it send corrupted data that make the driver crazy but not the imagePROGRAF Advanced Preview ?
    So, if any user of Canon iPF5000 + Mac OS 10.8 + Lightroom is around, please share your experience.
    And if any Apple, Adobe or Canon engineer read this, please try to fix this.
    Happy printing,
    Amaury

    It's different how applications write print data. If you use Advanced Preview from the driver then it calculates already the output which afterwards is only sent to the printer.
    Have you once tried to print with fast graphic process switched off (option of advanced settings)?
    Hope it helps

  • Memory Leak in BI SDK with XMLA Connector ?

    Hi,
    I am using BI SDK 3.5 with XMLA Connector. I noticed that in com.sap.ip.bi.sdk.dac.connector.xmla.impl.Connection class, the LocalTransaction object is rollbacked when the close() method is called.
    This makes a call to the endTransaction() method of Repository class with "true" parameter and leads to informations storage into a RepositoryDBMemory instance.
    The only way I found to avoid this is to call the endTransaction() method with "false" as parameter, which is what is done in commit() method of the LocalTransaction class.
    So, I tried to commit the transaction before closing the connection but in XMLA mode, the getLocalTransaction() method throws an BIResourceException so it is impossible to commit it. This is the first issue.
    Second issue: it seems that data hold by the DataSetContentHandler is not freed. I tried using SAP Parser, Xerces, Java Parser but it has no effect. I hava a MDX query that returns 13000 lines, the XML file size is about 15Mo.
    In a for loop with 10 operations, it leads to a OutOfMemory error quickly (only 7 iterations OK with -Xmx256m -Xms256m options). On each iteration, the memory grows about 25 to 30Mo !
    For the first point, I do not call the close method on the connection object and it is garbage collected (but, in my opinion, it is quite strange not calling the close() method on a connection object).
    For the second one (DataSetContentHandler), I have no idea. Has someone already encounter this problem ? The Netbeans profiler tells me it is this object that holds all java.lang.String objects. Is it right ?
    I saw in DataSetContentHandler class that it has two static fields: one for the row cursor of the dataset, the other one for column cursor. Why ? Is it OK in a multi-threaded context ?
    <b>This is urgent as we will not put the project in production mode with such a memory leak ! We must find the problem very quickly.</b>
    Thanks in advance for any help you might give to me !

    I found the same thing. Tracing the execution back I found the only place this function was called was as part of the setup, so you shouldn't have to worry about it getting called multiple times and leaking memory. The trouble seems to be when the AudioPlayer dealloc method is called, the memory is not cleaned up.
    My fix was to modify the dealloc in AudioQueueObject to check to see if audioLevels is nil and, if not, free it. This seems to have fixed the problem.

  • Plugin-container.exe takes over and uses 100% of my CPU locking me out and leaving my PC non-functioning. Is this a bug, or a memory leak, in the Firefox software? Can anything be done to fix this problem?

    In looking at Windows Task Manager I found that plugin-container.exe was taking over 100% of my CPU and my system was frozen. Is this a memory leak or other bug?

    Thank you! I have been having problems with Adobe Flash since downloading the new 11.1 version. I will download it again and reinstall it, hopefully that will correct the problem.

  • Memory leaks in NSURLConnection when using with ssl.

    Hi,
    I am experiencing a memory leak while using nsurlconnection with https request.
    I have a web-service over http and as well as HTTPS. When i call the web-service with HTTP i don't get any memory leak while when I call the web-service over HTTPS i got memory leaks, responsible library for this memory leak is cfnnetwork and responsible caller is nsurlrequest::setsslrequest.
    I just wanna make sure that should we have to set any property in nsurl for HTTPS request..
    I will be really helpful If someone can help me out.
    thanks in advance.

    I get the same(Or similar) issue... 48 Bytes for every call is being leaked. Instruments says that it's NSURLConnection that's leaking an NSString somewhere... Blowed if I can find why, build and analyse doesn't complain about that piece of code (Except that I'm releasing the url request late... i.e. by the caller instead of the method that allocates it. Naughty I know, but autorelease'ing the object had the same problem).
    This is on the simulator BTW...

  • Memory leak while debugging but not in release version

    I have an Adobe AIR application that must load and unload multiple external swfs, and it must run for hours.
    I had an issue where there was a memory leak. I tried all kinds of fixes, including rolling back SDKs and Adobe Runtime,
    but every time I tested in Flashbuilder, the memory would climb, and with each unload a FlexLoader would stay in memory.
    Finally I tried creating a release build, and low and behold the memory did not climb. It stayed the same even under stress testing.
    So evidently, the memory leak had to do with debug version, and once it was a release version, the leak disappeared.

    UPDATE: The problem was with the external swfs being loaded into the main application.
    If I compiled them in debug, they leaked. In release version they did not.

  • How can memory leaks occur?

    Hi,
    I was just wondering how a memory leak can occur in Java. The garbage collector is supposed to free up all unused variables, so under what circumstances can it happen?

    This is not technically a "memory leak". I've seen
    this called "loitering objects", which conjures upa
    vivid picture: objects hanging around with nothingto
    do...I think it's the classic java memory leak. A bug in
    a program that prevents the freeing up of memory that
    it no longer needs.Yes, but it's not what is traditionally termed a memory leak.
    A real memory leak is memory that's claimed by the program but no longer accessible to the program for freeing up.
    That can in Java (where what we call a program isn't a complete program but runs inside a virtual machine which handles memory allocation and deallocation) only happen if there's a flaw in the JVM itself which causes errors in memory deallocation (so most likely a flaw in the garbage collector).
    In Java the objects you create are always out there somewhere where something can reach them so as to prevent them from being available to the garbage collector.
    Different cause, same effect in that in both cases memory isn't getting freed for reuse.

  • 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 with swf generated by Xcelsius 4.5?

    Hello,
    I've experienced some memory problems with swf generated with Xcelsius 4.5. I'm using Windows Vista and Internet Explorer 7.
    I noticed that every time I refresh my dashboard using the F5 key, the memory used by the Internet Explorer process increases (or doubles).So, in case I need to refresh my dashboard many times, the memory used by the browser becomes definitely too much and compromises my system stability.
    Does anyone have experienced this problem? Is this a memory leak? Is there a way to fix this problem?
    Thank you,

    That's the trick who does it, thank you!

  • [Bug?] X-Control Memory Leak with Large Data Array

    [LV2009]
    [Cross-posted to LAVA]
    I have found that if I pass a large data array (~4MB in this example) into an X-Control, it causes massive memory allocations (1 GB+).
    Is this a known issue?
    The X-Control in the video was created, then the Data.ctl was changed to 2D Array - it has not been edited in any other way.
    I also compare the allocations to that of a native 2D Array (which is only ~4MB).
    Note: I jiggled the Windows Task Manager about so that JING would update correctly, its a bit slow, but it essentially just keeps rolling up and doesn't stop.
    Demo code attached.
    Cheers

    X Control Bug [LV2009].zip ‏42 KB

    Hi Jon (cool name) 
    Thank you very much for your reply. We came to this conclusion in the cross post and it is good to have it confirmed by LabVIEW R&D. Your response is also similar to that of my AE which I got this morning as well - see below:
    Note: Your reference number is included in the Subject field of this
    message. It is very important that you do not remove or modify this
    reference number, or your message may be returned to you.
    Hi Jon,
    You probably found some information from the forum. The US engineer has gotten back and he said that unfortunately that's expected behaviour after they have conducted some tests and this is what he replied:
    "X Controls in the background use events structures. In particular the Data Change Event is called when the value of the XControl changes (writing to the terminal, local variable, or value change property). What is happening in this case is the XControl is getting called to fast with a large set of data that the event structure is queuing the events and data that a memory leak is produced. It is, unfortunately, expect behavior. The main work around for the customer in this case is not call the XControl as often. Another possibility is to use the Synchronous Display Property to defer updates to the Xcontrol, this might slow down a leak."
    He would also like to know if you can provide with more details how you are using the Xcontrol, perhaps there is a better way. Please refer to the link below for synchronous display. Thank you.
    http://zone.ni.com/reference/en-XX/help/371361G-01/lvprop/control_synchronous_display/
    In my application I updated the X-Control @ 1Hz and it allocated at MBs/s up to 1+GB before it crashed, all within a few hours. That is why I called it a leak. I am really worried that if this CAR gets killed, there will still be an issue lingering that makes using X-Controls a major problem under the above conditions. I have had to pull two sets of libraries from my code because of this - when they got replaced with native LabVIEW controls the leak when away (but I lost reuse and encapsulation etc...).
    Anyways, I really want to use X-Control tho (now and in the future) as I like all other aspect of them. If you do not consider this a leak, can a different #CAR be raised that may modify the existing behavior? I offer the suggestion (in the cross-post) that the data be ignored rather than queued? Similar to Christian's idea, but for X-Controls. Maybe as an option?
    I look forward to discussing this with you further.

  • Memory leak in Flash with Win7, IE9, 64bit

    I have been having an issue for quite some time on 2 different computers. Both of them are Windows 7 64bit and use IE9.
    Generally I have 1 - 5 tabs open in IE at any given time. Usually one of them is a tab for Yahoo Mail. Other tabs are related to whatever I may be searching for or doing at that time, so pretty varied. Throughout the day at random times I will begin to get a grey icon for anywhere on some tabs where there is supposed to be a flash video (like the ad in the right side of the Yahoo Mail tab)... When it happens I can open Task Manager in windows and I notice that 1 or two "iexplore.exe *32" processes have memory consumed in excess of 600,000K. When I end those processes I am again able to see any flash videos that need to be viewed.
    If I leave Task Manager open throughout the day I can see the memory consumption increase on various tabs until I cannot see any more flash videos or even open new tabs in IE until I end those processes. Further, the memory does not get released if I just close the tabs in IE, but I must either end the specific process or close all tabs in IE so that IE is completely unloaded.
    I have since uninstalled the Flash player and the issue has gone away. I can re-install the flash player and the issue returns. Can you please help? This has been a huge annoyance and I had hoped that it would be fixed sooner or later. Unfortunately it has not been fixed and has finally prompted me to post something....

    First, I just wanted to follow up on this thread and let you guys know that we'll continue to look into it.  I also want to clarify some player behavior, and provide tips for helping to identify a defect that we can take action on.
    Whenever you refresh/reload a tab, the browser should signal to us that our process is being destroyed, at which point we would release all of our resources and shut down.  SergeStone's comment above makes it sound like this might not be happening in a particular case.  I'm going to build out a few tests this week to explore this in more detail, and I'll follow up with results.
    Also, it's worth discussing the difference between memory consumption and memory leaks.  Flash Player is designed to consume a percentage of your available memory.  If you have a 32-bit machine with 2GB of RAM, we're going to consume a lot less memory than a 64-bit system with 16GB of RAM. 
    Not all Flash content is authored well.  If the ActionScript developer is continuously loading objects into their SWF and never releasing them (a slide-show is a good simplistic example), you'll see a steady usage increase as each new object loads in.  You should also see that evenutally, our automatic Garbage Collection process will kick in.  Memory will peak out, and then you'll see a short CPU spike as we look at all of the available objects and cull as many unused ones as possible, consumed memory will dip down significantly (as long as we can cull stuff), and then start growing again until the next time GC kicks in.  We tend to do this judiciously, as poorly-timed GC can cause games to stutter if it happens when lots of things are moving around on the display and you don't have a lot of available CPU.
    If it's our bug, it should be straightforward to fix, and I can follow up to this thread with a beta build for you guys to evaluate once we have one available.  In the meantime, it would be interesting to know if you're seeing the problem on our current Beta builds (which is where we would do the work). 
    Here's a link to the latest Beta download:
    http://labs.adobe.com/downloads/flashplayer11-5.html
    Also, the simplest example is the most actionable.  If you can find a situation where a site in a single tab reproduces the problem, that's a quick and easy thing to deal with.  If the repro case involves opening seven tabs and waiting six hours, someone needs to repeat that over and over, until they can isolate what content experiences the problem and then iterate a bunch more with a debugger attached to try and isolate the root cause.  The more complicated the content, the more difficult that is.
    Secondly, I wanted to offer some actionable suggestions that you could use now to work around this issue. 
    Try Firefox or Chrome.  Both of these browsers run Flash Player as a separate process.
    For those of you using Performance Monitor and other tools to measure, you can directly observe the resources used by Flash Player
    For the folks concerned about Bookmarks synchronization, both Firefox and Chrome provide native bookmark syncing and import from IE mechanisms. 
    Xmarks is a really nice, free utility that provides cross-browser, cross-platform bookmark synchronization.
    Thanks,
    Jeromie Clark

  • 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,

  • Memory Leak in .swf

    Memory Leak issue with CS4
    Using CS4, we have a memory leak and I can not find the
    source of the problem.
    http://tiny.cc/O7D3e here is the
    link to the testing site. If you take a look at your task manager
    you will see it your RAM will continue to increase even after two
    or three cycles. It does not stabilize.
    We are using FlashEff | Flash Effects Component in order to
    generate the smooth transitions. However, I have done some
    debugging and even completely deleted the plug n from the file and
    it still continually leaks memory. Does anyone have any possible
    solutions or causes for this.

    One idea - there is a separate stack of memory in the flash
    player where loaded classes in separate application domains exist,
    and these classes are not being garbage collected....however, there
    is a line in adobe's documentation here:
    http://livedocs.adobe.com/flash/9.0/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Liv eDocs_Parts&file=00000327.html
    under "Usage C" :
    quote:
    Having a new application domain also allows you to unload all
    the class definitions for garbage collection, if you can ensure
    that you do not continue to have references to the child SWF.
    Given that, as far as I can see from this code, there is no
    reference to the loaded .swf maintained....it seems to me like the
    loaded data (graphical assets AND classes) should be garbage
    collected - but, while you WILL see a slight drop in memory after
    the removal of the SWF, the overall memory continues to increase
    the more you do it. Could Adobe be mistaken?

  • Bug:4705928 PLSQL: Memory leak using small varrays

    We have Oracle version 10.2.0.1.0
    We have a problem with a procedure.
    In our scenario we make use of VARRAY in the procedure to pass some filter parameters to a select distinct querying a view made on three tables.
    Unfotunately not always execution it is successful.
    Sometimes it returns wrong value (0 for the count parameter), sometimes (rarely) the server stops working.
    We suspect that this is caused by a bug fixed in versione 10.2.0.3.0
    Bug:4705928 PLSQL: Memory leak using small varrays when trimming the whole collection and inserting into it in a loop
    We suspect this becasue we made two procedure the first (spProductCount) uses a function (fnProductFilter) to calculate the values of a varray and passes them into the select,
    while in the second procedure (spProductCount2) parameters are passed directly into the statement without varray
    and there are failures only in the first procedure.
    On the other hand on another server 10.2.0.1.0 we never have this problem.
    The instance manifesting the bug runs under shared mode, while the other is under dedicated mode.
    Turning the first one to dedicated mode makes the bugs disapear.
    Unfortunately this is not a solution.
    In the sample there are the three table with all constraints, the view, tha varray custom type, the function and the two procedures.
    Is there someone that may examine our sample and tell us if the pl/sql code corresponds to the bug desciption.
    We also want to know if it's possibile that the same server running under different mode (SHARED/DEDICATED) doesn't behave the same way.

    Using VARRAY was the only way I found to transform comma seprated text values (e.g. "'abc', 'def', '123'") in a collection of strings.A varray is just a functionally crippled version of a nested table collection type, with a defined limit you probably don't need. (Why 100 specifically?) Instead of
    CREATE OR REPLACE TYPE varray_params AS VARRAY(100) OF NVARCHAR2(1000);try
    CREATE OR REPLACE TYPE array_params AS TABLE OF NVARCHAR2(1000);I don't know whether that will solve the problem but at least it'll be a slightly more useful type.
    What makes you think it's a memory leak specifically? Do you observe session PGA memory use going up more than it should?
    btw good luck with all those quoted column names. I wouldn't like to have to work with those, although they do make the forum more colourful.
