Version 7.3 memory leaks Windows 8 then crashes

Hello, There are already some threads about this, but they mention Windows 7. I can confirm the memory leak (it gets up to 1.5 gb then crashes) is happening on windows 8 and windows 8.1. This issue wasn't present for skype 7.2.0.103 , it is present for 7.3 and also for 7.4.0.102 . It leaks for about 0.6MB per second , it constantly writes to disk 0.3 MB/S and uses ~12% CPU. This behavior happens only after I'm logged in. No calls, no messages, just staying logged in is sufficient. Furhtermore, the memory leaked by Skype is not returning to the system, so I end up having 75% memory used on a 16 GB machine after restarting skype several times (because it crashes and I need skype to communicate with my contacts constantly). Please provide me with a link to download 7.2 (since it works). I had this issue with Skype 7.3 and in 7.4 nothing got solved, so please give me a link to something that works rather that something that's shiny but broken. Thank you

The memory leak is still occuring in 7.6.0+.
Downgraded to 7.2.0.103 and it still does not prevent memory leak. Eventually it crashes around 1100MB of RAM usage on my system. Validated everything is working like directx, etc. I think this is a Microsoft Windows 8.1 bug, and not just a Skype memory leak issue, as I have seen one other application do the exact same thing (grow to 1100MB and crash). Time to go bug Microsoft for a solution... oh wait... Skype is a Microsoft product.

  • Media Encoder is a memory leak - windows

    Applies to: Version 5.5.1.12 - 64 bit, Windows (Most likely earlier versions too)
    Reproducing the problem:
    Start Media Encoder as a standalone application by double clicking the icon.
    Close the window (by clicking the 'x' in the top-right corner) of Media Encoder.
    It does just that: closes the window. It does not close the process.
    The process now has no window-handle, thus the user can not access it.
    When user starts the application again, another process is created.
    Thus the previous process becomes a memory leak.
    Workaround:
    Open Windows Task Manager by pressing Ctrl-Alt-Del keys simultaniously then selecting Task Manager
    Click the 'Processes' tab
    Highlight 'Adobe Media Encoder.exe'
    Click 'End Process'
    Ignore the warning and kill the process

    Bill, Sometimes it takes AME and related components up to 30 seconds to close various processes.  If you close the app and immediately start a new instance, the old process sees that AME is still running and may not shut down it's process until you shut down your computer.  So give it a little time after shutdown to see if that helps.  That said, there are situations that I have seen myself that AME would not close all processes in background.  In many of those cases, it had to do with dynamic link and what type of files or assets you opend up and what application launches AME.  Sometimes when AME is launched by other applications like Premiere Pro, it leaves a process alive in case PPro is using it. but if you close all Adobe apps, it should close your process as well. Over the past few cycles, we have worked on improving processes. Let me know if the above info doesn't help.

  • Having problems opening iTunes. It tells me to reopen a window and then crashes

    I open iTunes and a pop up box informs me to re-open itunes in another window and then it crashes with a report of the crash.

    To access a second (or more) library, hold down the
    Shift key when launching iTunes 7. In the resulting
    dialogue you will get the option to create a new
    library or navigate to the other Library. The default
    location for your library files is \Documents and
    Settings\Username\My Documents\My Music\iTunes. The
    files will be called something along the lines of
    iTunes Library.itl
    It worked! Thank you so much... I thought I would have to go through and import all of my songs one by one again.
    Again, thank you! I really appreciate it!

  • Tuxedo Memory Leak Issue (Tuxedo 8.1 - Windows Server 2003)

    Hi
    We are running tuxedo 8.1, 32 bit with patch level 258 in our windows server 2003 based production environment. We are currently facing an issue where the memory usage of machine slowly keeps on going higher and higher eventually resulting in “Memory Allocation Failure” to tuxedo servers. We then have to do a complete restart of tuxedo which stabilizes the system for other few days.
    We have been analyzing the our source code in development/test environment using different tools like a customized Alzheimer tool and IBM purify but both tools reported no memory leaks. We then developed a test tuxedo server exposing a tuxedo service which simply allocates a memory to a response buffer and then returns the response buffer. I then configured tuxedo queue with same name “MEMTEST3” and configured a TMQForward server to call this “MEMTEST3” service every time a message is en-queued to the MEMTEST3 queue.
    unsigned long _LIBENTRY ulTPAlloc(FBFR32 **ppc, long size)
    unsigned long ulRes = MSG_SUCCESS_c;
    ppc = (FBFR32 ) tpalloc("FML32", (char *) 0, size);
    if (*ppc == (FBFR32 *) 0) {
    vLogMessage(hGetLogHandle(), MSG_MEM_ALLOC_ERR_c, (char *) 0, (Event_t *) 0,
    BM_NOSUPPRESS_c, size);
    ulRes = MSG_MEM_ALLOC_ERR_c;
    return (ulRes);
    /*==============================================================================
    Service MEMTEST2
    ==============================================================================*/
    void MEMTEST3(TPSVCINFO *pRequest)
    FBFR32 *pFmlResponse = NULL;
    FBFR32 *pFml = NULL;
    unsigned long ulRes = MSG_SUCCESS_c;
    unsigned long ulActionCode = 0;
    int iExitValue = 0;
    long lTpurcode = 0;
    FBFR32 *pFmlNULL = NULL;
    userlog("Starting MEMTEST3 service.");
    if (pRequest == NULL || pRequest->data == NULL)
    vLogMessage(hGetLogHandle(), MSG_API_ARGS_ERR_c, NULL, NULL, BM_NOSUPPRESS_c);
    ulRes = MSG_API_ARGS_ERR_c;
    else
    pFml = (FBFR32 *) pRequest->data;
    userlog("MEMTEST3: GET THE MEM");
    ulRes = ulTPAlloc(&pFmlResponse, 1024);
    userlog("Ending MEMTEST3 service.");
    tpreturn( iExitValue, lTpurcode, ( char * ) pFmlResponse , 0L, 0L );
    While I was en-queuing the messages to the queue, I kept on monitoring the memory usage of the server hosting the service. What I observed was that I saw an initial hike in the usage of memory of the server followed by small jumps in memory increase. I kept on monitoring the server for a long time and the memory was never returned. What I suspect is that there is memory leak in tuxedo TMQforward process as it never released the memory allocated in the service.
    Can anyone help how this situation can be avoided ?
    Kind Regards,
    Asim

    Hi Todd,
    Also as well as my previous question, I also found your reply to another user posting something similar at Re: Memory leaks in Tuxedo libraries
    You mention that:
    In general Tuxedo will free anything it allocates, although there are cases where memory is allocated and not freed because:
    +1) it is one time or a fixed number of times allocations that will not continue to grow, and freeing up the memory just before exiting isn't of any benefit.+
    +2) the memory is under Tuxedo's memory management functions where we manage our own look aside lists to provide better buffer allocation performance and again freeing these before process termination is of little benefit.+
    Our code does only issue TPALLOC once and then a TPRETURN - could point (1) of your comment above also be something of concern to us, where we would observe a continuous growth of memory usage?
    I know it may sound like a stupid question but do we need to run our code 20,000 times before memory gets freed?
    Kind Regards,
    Asim

  • New Memory Leak Detector released

    This week we released an updated version of the Memory Leak Detector. It now features a much improved graphical user interface as well as more powerful ways to track down memory leaks.
    The tool is designed to help you find memory leaks in production type environments without causing much overhead. It allows you to attach to a running JRockit process, analyze the heap, and detach, leaving the process running at full speed again.
    There is an article on dev2dev which describes the tool in more detail: http://dev2dev.bea.com/pub/a/2005/06/memory_leaks.html

  • Winverifytrust memory leaks?

    I had a question on winverifytrust's catalog signing. We are using winverifytrust and we don't call WTD_ACTION_STATE_CLOSE after the call, we call it only if hWVTStateData is not NULL. What we see is that system memory consumption continues to rise in spikes
    The consumption rises, then settles down to a steady state and then rises again after some time and then rises again after a longer period with a larger amount. We believe this may be the side-effect of internal caching done by the catalog signature trust
    API. Could someone help confirm the behaviour
    1. Is this expected behaviour?
    2. Is our usage of the API (not calling STATE_ACTION_CLOSE unconditionally correct?)
    3. Does internal caching behave this way, if so does it reach a steady state where the cache size will not grow beyond a certain limit, can that limit be predicted?
    Thanks,
    Balbir

    Hi,
    Could you please have a share for which developer language we are using here?
    Regarding the issue here, we'd better seek help in some developer forum for a better assistance.
    MSDN troubleshooting and support

  • Memory leak when using DB_DBT_MALLOC in CDB.

    Hello!
    Recently when I'm using Berkeley DB CDB and set the value Dbt DB_DBT_MALLOC, I noticed that the app's memory keeps growing during the db.get while;
    I found that many codes on the internet use the syntax free(value.get_data()), but when I tried to free the value.get_data(), I always got an interruption error.
    It's OK when I'm using the DB_DBT_USERMEM flag. So I just get very confused about the DB_DBT_MALLOC and DB_DBT_REALLOC.
    And also, I wonder why there's no memory leak problem when we use the single thread BDB. I think BDB cannot free the value.data pointer too in single thread before the app finish using it, then why our apps don't need to free the data afterwards?
    Thanks a lot in advance!

    You should use free() to free the DBT memory allocated via DB_DBT_MALLOC. You should do that after each Db::get() operation (and of course after finishing processing/using the data), otherwise you will loose the pointer to the memory previously allocated if you happen to reuse the DBT with DB_DBT_MALLOC (the data field will point to a new memory address).
    Alternatively you could use DB_DBT_REALLOC or DB_DBT_USERMEM.
    Note that there are small structures that BDB creates in the environment regions that only get freed/cleaned when the environment is closed.
    If you suspect that there is a memory leak inside the BDB code, make sure you rebuild Berkeley DB using the following configuration options (along with the others you use) when building: enable-debug, enable-umrw. Than, run the program under a memory leak detection utility, like Valgrind (allow the application to open and close the BDB environment) and see if there are any leaks reported.
    If memory leaks are reported, then put together a small stand-alone test case program that demonstrates the leaks, and post it here.
    Regards,
    Andrei

  • Finding memory leaks in java

    Hello,
    I have a memory leak in my application. I have found other memory leaks in the software using JProfiler, but I have a problem with JProfiler finding this one. My biggest problem is the JProfiler itself. If I use short runs, the JProfiler works fine. If I run my application for more than half a day, the JProfiler eats up memory and after a while it stops responding.
    I tried JProbe, but after profiling my application for 18 hours straight, it got buggy and wouldn't work correctly. It also ate up alot of memory, and couldn't process my snapshot after 18 hours of run. I saved all snapshots, and restarted JProbe. The initial snapshot was read correctly, but the final snapshot threw an NegativeArraySizeException.
    So, now I am looking for other tools which are able to find memory leaks without hanging or crashing after running 24 hours. Any recommendations?

    I dont know any other profiler you can use, but how about using the divide and conquer approach?
    Disable a significant section of your application and let it run for a day. If the leak occurs, its in the non disabled part.
    If it doesn't, its in the disabled part. Next, enable all the code. Then disable about half of the half that failed and try that. Continue doing so until
    you isolate the code enough that you can look at it and hopefully find the problem. Note you will need to keep track of what you previously enabled and disabled as a test (I put comments in the code).
    Alternately, you can look at functions that perform complex functionality that you suspect might be the problem and have the function return
    dummy data rather than perform the functionality. If the leak goes away, its that function(s).
    Example:
    public String getComplexData(String arg1, String arg2){
    //this section bypasses the complex code and returns dummy data
    boolean x1= true;
    if(x1==true)
    return new String("some dummy data");
    //complex functionality goes here.
    Also of help would be to list everything that can cause a memory leak (I assume its a memory leak and not a resource leak such as not closing connections).
    Here are some ideas:
    1) persistant class variables that are a collection that have objects added to them but never deleted and allowed to be garbage collected
    such as static class variables, session scope variables, or application scope variables.
    2) An object tree where one of its nodes is never set to null to be garbage collected (such as a static class variable).
    If you are running a web application in a clustered enviornment, try running it on only one server.

  • How to fix huge iTunes memory leak in 64-bit Windows 7?

    iTunes likes to allocate as much as 1.6GB of memory on my dual-quad XEON 8GB 64-Bit Windows computer and then becomes unresponsive.
    This can happen several times a day and has been going on for as long as I can remember.  No other software that I use does this - only Apple's iTunes.  Each version I have installed of iTunes appears to have this same memory leak.  Currently I am running version 10.7.0.21.
    I love iTunes when it works.  But having to constantly kill and relaunch the app throughout the day is bringing me down.
    Searching for a fix for this on the internet just surfaces more and more complaints about this problem - but without a solution.
    Having written shrinkwrapped software for end users as well as for large corporations and governments for more than 25 years I know a thing or two about software.  A leak like this should take no more than a day or two to locate using modern software tools and double that to fix it.  So why with each new version of iTunes does this problem persist?  iTunes for Windows is the flagship software product Apple makes for non-Mac users - yet they continue to pass up each opportunity they have had over the years with each new release to fix this issue.  Why is this?
    Either the software engineers are not that good or they have been told NOT to spend time on this issue.  I personally believe that the engineers at Apple are very good, and therefore am left thinking that the latter is more likely the case.  Maybe this is to coax people to purchase a Mac so that they can finally run iTunes without these egregious memory leaks.  I would like to offer another issue to consider.
    Just as Amazon sold Kindles and Google sold Nexus tablets at low cost - not counting on margin for profit - but instead they wanted to saturate the marketplace with tools for making future purchases of content almost trivial to do with their devices.  Apple also counts on this model with their pricer hardware - but they also have iTunes.  Instead of trying to get people to switch to a MAC by continuing to avoid fixing this glaring issue in iTunes for Windows I would like to suggest that by allowing their engineers to address this issue that Apple will help keep Windows users from jumping ship to another music app.  The profit to be made by keeping those Windows users happy and wedded to the iTunes store is obvious.
    By continuing to keep this leak in iTunes for Windows all it does is lower my esteem for the company and start to make me wonder if the software is just as buggy on Macs.

    I have same issue. Ongoing for more than 1 year and currently running iTunes 11.3.
    My PC is Dell OptiPlex 990 I7 processor, 8GB ram, W7 64 [always keep things patched up to latest OS updates etc]
    I use this iTunes install to stream music videos etc to multiple appleTVs, ipads, iphones etc .. via Home Sharing
    Store all my media including music, videos and apps on separate NAS  .. so the iTunes running on PC is only doing the traffic cop role and streaming / using files stored on NAS .. creates lots of IO across my network
    Previous troubleshooting suggest possible contributing causes include
    a) podcast updates  .. until recently I had this auto updates on multiple podcast subscriptions, presumably the iTunes would flow this from the PC to save on the NAS across the network .. if the memory leak is in the iTunes network communication layer (?bonjour?)  this may be sensitive to IO that would not normally occur if the iTunes file saving was local on the same PC
    b) app updates .. have 200+ apps in my library and there is always a batch of updates .. some updates 100s of MB is size .. routinely see 500MB to 1GB of updates in single update run .. all my apps are
    c) streaming music / movies .. seems when we ramp up streamlining of music or movies . memory leak grows faster .. ie within hours of clean start
    c) large syncs of music or videos to ipads or iphones .. noticed that get big problems when I rebuild an ipad .. I typically have 60+ GB of data in terms of apps /  music / videos to load .. have to do rebuild in phases due to periodic lockups

  • Firefox has a memory leak and I need to update it, but I want to keep 3.5 because I don't like how the newest version of Firefox is set up.

    My computer is running low on RAM, and when I look at what processes are using the most memory, firefox is the number one using between 28,000 to 93,000k, so I'm guessing that it has a memory leak.
    And because of that memory leak I have to update firefox, however I really dislike the newest version of firefox and I'd prefer to stick with the version I have, which is 3.5.

    Often the memory problems are not just from Firefox in isolation, but partly relating to all the extensions available for it and then the videos and animations it runs on media rich sites.
    The first thing to do is to upgrade to firefox 3.6 which is at least a supported version (Maybe not for much longer)
    * see [[updating firefox]]
    Next version after 3.6 is 4, you should avoid that, it did have some memory problems, that were worse than 3,6 and firefox 4 is no longer secure or supported.
    The techies at Firefox have been working on memory problems recently and have made many improvements, but some of these improvements are only seen in the trial versions of Firefox.
    I would in fact suggest you upgrade to Firefox 5 the current release version (soon to be replaced with Firefox 6)
    I am able to run Firefox v3.6 to v8 on legacy XPs with less than 1GB RAM. Firefox in itself is not necessarily very demanding in terms of RAM. I am not sure what the figures are you are quoting, or whether they are high. ( Note 1Gb is in the order of 1 000 000 k )
    As for not liking the set-up of new versions of Firefox, there is quite abit that can be changed, maybe you would be able to configure it more to your liking with little effort.

  • Memory leak in ODBC Driver version 8.1.7.8?

    We have a web application connected to an 8.1.7 database on a MS Windows 2000 SP 2 server.
    We recently upgraded ODBC driver from 8.1.7.7 to 8.1.7.8 and found that we ran out of virtual memory.
    On further investigations, a simple refresh of our summary web page (going to the database to select a small recordset - even when there are only 2 records with 6 small VARCHAR2 fields) causes the virtual memory usage to increase by approximately 1Mb each refresh.
    The same refresh using driver 8.1.7.7 occasionally increases the VM usage by 4Kb!
    Is there a memory leak in ODBC driver version 8.1.7.8?

    Hello Thomas,
    thanks for your tips, but they did not help. Activating Connection Polling did not change anything. And opening another connection did not help, either. I did it the following way:
    Sub memtest2()
    Dim conODBC As New ADODB.Connection
    conODBC.ConnectionString = "Data Source='xxxx';User ID='xxx';Password='xxx'"
    conODBC.Open
    Dim Rs1 As Recordset, Rs2 As Recordset, DB1 As Database
    Set DB1 = CurrentDb
    Set Rs1 = DB1.OpenRecordset("select id from artikel")
    Do While Not Rs1.EOF
        Set Rs2 = DB1.OpenRecordset("select * from artikel where id=" & Rs1("id"))
        'do something
        Rs2.Close
        Set Rs2 = Nothing
        Rs1.MoveNext
    Loop
    Rs1.Close
    Set Rs1 = Nothing
    DB1.Close
    Set DB1 = Nothing
    conODBC.Close
    End Sub
    Perhaps one of you has another tip how this can be done.
    @Lukasz:
    using a seperate ADODB.Connection works fine, but that does not solve the problem itself. At first I would have to rewrite much code and the second much bigger thing is that the memory leak occurs even when working with bound forms in MS Access. For example: I have one large form with many subforms on it. If i go from record to record on this form the memory usage is increasing dramatically fast and there is no way to influence what kind of connection MS Access is using for bound forms.

  • Memory leak playing podcasts in iTunes 11.2, Windows 8.1 x64

    I've already uninstalled and reinstalled iTunes 11.2 64 bit.
    When I play a podcast it plays for a few minutes then iTunes freezes.  Watching it in task manager its obvious there's a memory leak.  Memory climbs steadily until about 1.6Gb when it dies.
    Any suggestions?
    Can we download earlier versions?

    Was hoping 11.2.2 would fix it. Nope, the memory leak is still there in the podcasts tab. The workaround is to refresh podcasts and jump to the music tab.

  • There appears to be a MAJOR issue (hang/memory leak) in "about:home", also known as the Firefox Start Page, in Firefox 26.0 on Windows!

    There appears to be a MAJOR issue (hang/memory leak) in "about:home", also known as the Firefox Start Page, in Firefox 26.0, on Windows!
    observed on:
    - Windows 7 x64 machine with 12GB RAM and high-performance CPU (core i7-920)
    - Virtual Machine guest running WinXP SP3 (in Oracle VirtualBox) on the same machine
    - Intel Atom D525 netbook with 4GB RAM, running Win7 x64
    Neither of these machines are connected via Sync or anything like that. The Firefox instance on the VM is a fresh/clean install.
    The problem:
    - 100% cpu usage for 10 seconds, memory usage (PF usage in XP) goes up to 1.7GB
    - if "about:home" is the Firefox Start Page, effectively it hangs the computer at Firefox startup for 10 seconds
    - if "about:home" is NOT the Firefox Start Page, startup is fine - BUT if I press the "home" button on the toolbar it loads "about:home" which causes the same issue again

    Thank you cor-el! Your suggestion has solved the problem on my WinXP VM which I was using to test, and I will soon confirm that it has also solved the problem on my primary Win7 desktop.
    To recap:
    - I set "browser.aboutHomeSnippets.updateUrl" to an empty string
    OLD VALUE: https://snippets.mozilla.com/%STARTPAGE_VERSION%/%NAME%/%VERSION%/%APPBUILDID%/%BUILD_TARGET%/%LOCALE%/%CHANNEL%/%OS_VERSION%/%DISTRIBUTION%/%DISTRIBUTION_VERSION%/
    NEW VALUE: (blank)
    - I deleted the folder \storage\persistent\moz-safe-about+home under the Profile directory
    Actual folder name on WINDOWS XP:
    C:\Documents and Settings\<USERNAME>\Application Data\Mozilla\Firefox\Profiles\<PROFILENAME>\storage\persistent\moz-safe-about+home
    However I have a concern that the '''OLD VALUE''' of "browser.aboutHomeSnippets.updateUrl" will creep back in, in a future update! Can you communicate this issue to someone on the development team?

  • Are you guys going to fix the memory leak in version 6

    Hi I was wondering if you guys were going to fix the huge memory leak in Firefox 6. As of now I use windows Vista 32bit Ultimate and Firefox is using 164MB of memory to view www.google.com. I'm sorta confused also on how SLOW the browser is. I never seen F.F act this way since F.F 6. I'm hoping that this will be resolved in version 7 cuz this is not cool so slow in all.

    On the "flip-side", I had the smoothest and quickest iTunes upgrade/install ever.  This was on my Windows 7 Professional, 64bit system.
    That you performed an assumedly 'clean' reinstall of your OS, is not a good sign.  Obviously, iTunes doesn't like something within your system.
    Here are the next steps that I would take if in your position:
    -  Are you absolutely positive that you have the 64bit version of iTunes?
    -  Re-download a new copy of the 64bit version of iTunes 10.5
    -  Try downloading iTunes from one of the 'mirror sites' - FileHippo is good
    -  Call your PC's manufacturer and see if they are aware of any conflicts with your specific machine's build with respect to iTunes
    -  Temporarily use another PC (if available) to get your iPhones up and running
    Best of Luck
